A rectangular field has a length of 24 meters and a width of 18 meters. If a path of 3 meters wide is built around it (outside the field), what is the area of the path?
A.250 sq m
B.270 sq m
C.288 sq m
D.300 sq m
Solution
Area of a path
The path is built outside the field, so it adds 3 m on each of the four sides.
Outer length m and outer width m.
Area of the outer rectangle sq m.
Area of the field sq m.
Area of the path =720-432=288 sq m, so option (c) is correct.
27
A square park has a perimeter of 24 meters. What is the area of the park ?
A.24 sq m
B.36 sq m
C.30 sq m
D.48 sq m
Solution
Area of a square
For a square, perimeter , where a is the side.
So 4a=24, which gives m.
Area of a square sq m, so option (b) is correct.
28
During an office meeting , a senior accidentally drops the files on a junior's desk. What's the best reaction?
A.Help gather the files and respond politely
B.Get irritated and blame the senior
C.Laugh loudly at the situation
D.Walk away without helping
Solution
Workplace behaviour
The files fell by accident, so no one is at fault and the question is only about the right response.
The mature workplace reaction is to help gather the files and reply politely - it settles the matter at once and keeps the working relationship healthy.
Getting irritated and blaming the senior, laughing loudly, or walking away are all unhelpful and unprofessional.
Hence option (a) is correct.
29
In this type of questions, question is provided with substitutes for various mathematical symbols, followed by a question involving calculation of an expression or choosing the correct/ incorrect equation. You have to put the real signs in the given equation and then solve the questions as required.
If '%' stands for '+', '&' stands for '-', 'S' stands for ' ', ' ' stands for ' ', then find the value of:
?
A.-103
B.-104
C.-102
D.106
Solution
Symbol substitution
Put the real sign in place of every substitute symbol: the symbol standing for division becomes and the symbol standing for multiplication becomes .
The expression therefore reads .
By BODMAS, division and multiplication are done before subtraction.
and .
So the value =4-108=-104, and option (b) is correct.
30
In a certain code, "BALL" is written as "CBMM". How is "CROW" written in that code?
A.DSPX
B.DQPX
C.DSQX
D.DPPX
Solution
Letter coding
Compare BALL with CBMM letter by letter: B→C, A→B, L→M, L→M.
Every letter moves one step forward in the alphabet, so the rule is +1.
Apply the same +1 shift to CROW: C→D, R→S, O→P, W→X.
So CROW is written as DSPX, and option (a) is correct.
31
Find the odd one out:
9, 16, 25, 30, 36
A.16
B.25
C.36
D.30
Solution
Odd one out
Test each number for being a perfect square: , , , .
30 lies between and , so it is not the square of any whole number.
Hence 30 is the odd one out, and option (d) is correct.
32
Choose the related word from the given alternatives.
NATO : Brussels :: ASEAN : ?
A.Jakarta
B.Bangkok
C.Kathmandu
D.Vienna
Solution
Organisation and headquarters
The relation is 'organisation : city where its headquarters is located'.
NATO, the North Atlantic Treaty Organization, has its headquarters at Brussels in Belgium.
ASEAN, the Association of Southeast Asian Nations, has its Secretariat at Jakarta in Indonesia.
Bangkok is only where ASEAN was founded in 1967, Kathmandu is the SAARC headquarters and Vienna hosts OPEC and the IAEA, so option (a) is correct.
33
Pick the correct options from the given alternatives
INDIA : AIDNI : : PATNA : ?
A.APTNA
B.ANPTA
C.ANPAT
D.ANTAP
Solution
Word reversal
Write the letters of INDIA backwards: I-N-D-I-A read from the end gives A-I-D-N-I, which is exactly the given code AIDNI.
So the rule is simply to reverse the order of the letters.
Reversing PATNA: P-A-T-N-A read from the end gives A-N-T-A-P.
Hence the answer is ANTAP, and option (d) is correct.
34
Select the related letter from the given alternatives
EARTH : BXOPD : : VENUS : ?
A.SBKQP
B.SBKOQ
C.SBKQO
D.SUNEV
Solution
Letter-cluster coding
Compare EARTH with BXOPD position by position: E→B, A→X, R→O, T→P, H→D.
The first three letters move 3 places backward and the last two move 4 places backward; the alphabet is treated as circular, so A moved 3 back gives X.
The pattern of shifts is therefore .
Apply it to VENUS: V-3=S, E-3=B, N-3=K, U-4=Q, S-4=O.
So VENUS is coded as SBKQO, and option (c) is correct; options (a) and (b) merely swap the last two letters.
35
Select the correct options from the given alternatives 91, 79, 64, 46 ....
A.26
B.25
C.35
D.21
Solution
Number series
Take the differences between consecutive terms: 91-79=12, 79-64=15, 64-46=18.
These differences themselves rise by 3 each time, so the next difference is 18+3=21.
Hence the next term =46-21=25, and option (b) is correct.
36
Six people were seated around a circular table facing inwards. B is seated to the immediate right of D.F is seated to the immediate right of A. E is seated to the immediate right of and E are not seated opposite to each other. F and C are not immediate neighbors.
Who is seated third to the left of ?
A.C
B.B
C.D
D.E
Solution
Circular seating
When people face the centre, a person's right hand points anticlockwise, so 'X is to the immediate right of Y' means X comes just before Y in clockwise order.
The three clues therefore give the clockwise blocks (B, D), (F, A) and (E, C), which must be placed round the table in some order.
If the order were B, D, E, C, F, A then C and F would sit next to each other, which the last clue forbids.
So the clockwise order is B, D, F, A, E, C; here B faces A and E faces D, so B and E are not opposite - both conditions are satisfied.
Facing the centre, 'to the left' means moving clockwise: from A the first is E, the second is C and the third is B.
Hence B is seated third to the left of A, and option (b) is correct.
37
You are given a Master Address (MA) from official records. Your task is to identify the correct candidate address that matches exactly with the master address in terms of formatting, punctuation, spelling, and structure.
Master Address (MA): Shop No. G-15, City Centre Mall, 120 Ft. Road, Jayanagar, Pune - 411001
Candidate Addresses:
A.Shop No. G-15, City Centre Mall, 220 Ft. Road, Jayanagar, Pune - 411001
B.Shop No. G-15, City Centre Mall, 120 Ft. Road, Jayanagar, Pune - 411001
C.Shop No. G-16, City Centre Mall, 120 Feet Road, Jayanagar, Pune - 411001
D.Shop No. G-15, City Center Mall, 120 Ft. Road, Jayanagar, Pune - 411002
Solution
Address matching
Compare each candidate with the master address element by element - shop number, mall name, road, locality and PIN code.
Option (a) changes the road number to 220 Ft. Road; option (c) changes the shop to G-16 and expands 'Ft.' into 'Feet'; option (d) spells 'Center' for 'Centre' and ends with PIN 411002.
Only option (b) reproduces every element exactly - Shop No. G-15, City Centre Mall, 120 Ft. Road, Jayanagar, Pune - 411001.
Hence option (b) is correct.
38
You are given a Master Address
(MA) from official records. Your task is to identify the correct candidate address that matches exactly with the master address in terms of formatting, punctuation, spelling, and structure.
Master Address (MA): 12/A, K.P. Towers, Anna Salai (Brigade Road), Bengaluru - 560001
Candidate Addresses:
A.12/A, KP Towers, Anna Salai (Brigade Road), Bengaluru - 560001
B.12/A, K.P. Towers, Anna Salai (Brigade Road), Bengaluru - 560001
C.12 A, K.P. Towers, Anna Salai (Brigade Road), Bengaluru - 560001
D.12/A, K.P. Towers, Anna Salai (Brigade Rd), Bengaluru - 560001
Solution
Address matching
Check four things in each candidate: the house number, the initials, the bracketed part and the PIN code.
Option (a) drops the full stops and writes 'KP Towers'; option (c) writes '12 A' with a space instead of '12/A'; option (d) shortens 'Brigade Road' to 'Brigade Rd'.
Option (b) keeps every character of the master address, punctuation included.
Hence option (b) is correct.
39
What comes next in the series:
2, 3, 5, 8, 13, ?
A.18
B.19
C.21
D.20
Solution
Number series
Add each pair of consecutive terms: 2+3=5, 3+5=8, 5+8=13.
Every term is the sum of the two terms before it, which is the Fibonacci pattern.
So the next term =8+13=21, and option (c) is correct.
40
You receive information about a disagreement between two colleagues in your office regarding a project. What would be the most fair and rational way to make a decision?
A.Support the colleague who is personally closer to you
B.Make a decision based on your feelings or personal preference
C.Examine the arguments and available facts of both sides and make a decision based on that
D.Completely avoid making any decision
Solution
Rational decision making
A fair decision must rest on evidence, not on personal closeness or on how one feels.
So the correct course is to hear both colleagues, weigh their arguments against the facts available, and then decide.
Siding with a friend (a) and going by personal preference (b) are both biased, while avoiding the decision (d) leaves the project stuck.
Hence option (c) is correct.
41
You have an earthquake relief vehicle that can evacuate only 8 people. There are 12 people waiting, including elderly, children, and healthy adults. Who should be given priority?
A.First come, first serve
B.Healthy adults, so they can help others later
C.Elderly and children
D.Random selection
Solution
Relief priority decision
Only 8 of the 12 waiting people can be lifted, so the seats must go to those who are least able to survive the wait on their own.
Elderly people and children have the lowest physical capacity to withstand aftershocks, cold, hunger or a long delay, so they form the most vulnerable group.
Healthy adults can wait, move out on foot and even help at the site, so evacuating them first would expose the weakest to greater danger.
'First come, first serve' and random selection ignore need altogether, which is exactly what a relief operation must not do.
Hence option (c) is correct.
42
Identify the next number.
1, 8, 27, 64, 125, ?
A.217
B.216
C.343
D.512
Solution
Number series (cubes)
Read the terms as powers rather than as differences: , , , and .
So the series is simply the cubes of consecutive natural numbers.
The next term must therefore be .
Option (a) 217 and option (c) break the order of the cubes.
Hence option (b) is correct.
43
Identify the next number in the sequence.
30, 56, 90, 132 , ?
A.178
B.182
C.192
D.202
Solution
Number series (differences)
Take the successive differences: 56-30=26, 90-56=34 and 132-90=42.
These differences themselves grow by 8 each time, so the next difference is 42+8=50.
Therefore the required term is 132+50=182.
The same rule can be seen as a product of consecutive numbers: , , , and .
Hence option (b) is correct.
44
8 Persons P1, P2, P3, P4, P5, P6, P7 and P8 are sitting in a row facing north (not necessarily in the same order). P1 is fifth to the left of P6. P4 is fifth to the right of P5. P1 is to the immediate left of P5. Only two boys are sitting between P8 and P4. P2 is third to the right of P7, P7 is an immediate neighbour of P1. Who is at third position from the right end of the row?
A.P3
B.P6
C.P8
D.P2
Solution
Linear seating arrangement
Number the seats 1 to 8 from the left end; everyone faces north, so left and right are as seen on the page.
P1 is immediately left of P5 and P4 is fifth to the right of P5, so P4 sits six places to the right of P1, while P6 sits five places to the right of P1.
A seat six places to the right of P1 must still lie in the row, so P1 can only be at seat 1 or seat 2.
P7 is a neighbour of P1. If P1 were at seat 1, its only neighbour is seat 2, which is already P5; so P1 is at seat 2 and P7 at seat 1.
Then P5 is at seat 3, P6 at seat 7 and P4 at seat 8, and P2, being third to the right of P7, is at seat 4.
Exactly two persons sit between P8 and P4 (seat 8), which puts P8 at seat 5, and the only person left, P3, takes seat 6.
Counting from the right end, seat 8 is first, seat 7 second and seat 6 third, and seat 6 is P3.
Hence option (a) is correct.
45
R walks 12 km straight. He turns left and walks 5 km . How far (in km ) is R now from the starting point?
A.13
B.15
C.17
D.18
Solution
Direction sense distance
Take the first stretch as due east: R walks 12 km east from the starting point.
Turning left while facing east means he now faces north, so the second stretch of 5 km is perpendicular to the first.
The two stretches form the legs of a right-angled triangle, so the direct distance is the hypotenuse: .
.
Hence option (a) is correct.
46
Select the option that is related to the second number in the same way as the third number is related to the fourth number and fifth number is related to sixth number.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
? : 5263 :: 6372 : 7214 :: 4831 : 5673
A.4419
B.4421
C.4423
D.4425
Solution
Number analogy
As the note directs, treat each number as a whole and compare the complete pairs.
In the second pair, 7214-6372=842, and in the third pair, 5673-4831=842.
So the rule is: second number = first number +842.
For the missing first number, 5263-842=4421.
Check: 4421+842=5263, which matches the given pair.
Hence option (b) is correct.
47
If '+' means '÷', '-' means '+', 'x' means ' - ' and ' ' means ' ', then ?
A.3
B.7
C.5
D.9
Solution
Symbol substitution
Replace every symbol by the meaning given: + becomes , - becomes +, becomes - and becomes .
So turns into .
Now apply BODMAS: and .
The expression becomes 9+12-18=21-18=3.
Hence option (a) is correct.
48
After interchanging the given two signs, what will be the value of the given equation?
and +
?
A.29
B.9
C.12
D.39
Solution
Interchanging signs
Interchanging the two given signs means writing wherever + appears and + wherever appears.
So becomes .
By BODMAS, do division and multiplication first: and .
The expression reduces to 5+10-6=15-6=9.
Hence option (b) is correct.
49
By interchanging the given two numbers (not digits) which of the following equation will NOT be correct?
3 and 6
I.
II.
A.Only I
B.Only II
C.Both I and II
D.Neither I nor II
Solution
Interchanging numbers
Interchanging the numbers 3 and 6 means every standalone 3 becomes 6 and every standalone 6 becomes 3; digits inside a bigger number such as 12 are untouched.
Equation I, , becomes .
By BODMAS, 12-6+4=10, which is not 18, so I is not correct.
Equation II, , becomes .
By BODMAS, 12+3-3=12, which is not 13, so II is not correct either.
Since both equations fail, option (c) is correct.
50
A word has been given in the question. This word CANNOT be formed by using the letters of the word given in one of the alternatives only. Select that alternative.
PEARL
A.PARCEL
B.PLAYER
C.PLEASE
D.PARLEY
Solution
Word formation
To form PEARL you need the five letters P, E, A, R and L.
PARCEL, PLAYER and PARLEY each contain all five of them, so PEARL can be formed from every one of these words.
PLEASE is made of P, L, E, A, S, E - it has no R, so PEARL cannot be formed from it.
Hence option (c) is correct.
