A father’s brother is an uncle.
Z is Y’s uncle — option (c).
6
Someone might accidentally get hurt while playing. What should you do?
A.Laugh
B.Apologize
C.Run away
D.Blame someone else
Solution
Ethics — accidental hurt
An accidental injury still calls for responsibility and concern.
The right response is to apologise and help the injured person.
Laughing, running away or blaming others is insensitive and evasive.
Hence option (b).
7
Find the odd one out:
A.2 $ 4 = 42
B.4 $ 6 = 100
C.7 $ 5 = 144
D.3 $ 2 = 25
Solution
Number puzzle (a + b)²
Rule: a $ b = (a + b)².
(4+6)² = 100 ✓, (7+5)² = 144 ✓, (3+2)² = 25 ✓.
But (2+4)² = 36, not 42 ✗.
Hence option (a).

Read the following statements carefully and identify the conclusion that follows.Statements:
All pencils are erasers.
Some erasers are sharp.
All sharp objects are pointed.
Conclusions:
I. Some erasers are pointed.
II. Some pencils are pointed.
A.Only I follows
B.Only II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Syllogism
Some erasers are sharp and all sharp objects are pointed, so those erasers are pointed — I follows.
Pencils lie inside the eraser group, but nothing puts them inside the SHARP part of it.
So II is not certain.
Hence Only I — option (a).
9

C.50 minutes
D.20 minutes
Solution
Machines and time
10 machines make 10 boxes in 10 minutes, so ONE machine makes ONE box in 10 minutes.
Each machine works independently on its own box.
So 100 machines making 100 boxes still need only 10 minutes.
Hence option (a).
16
You are a school teacher. A student suddenly becomes unconscious. What will be the first step?
A.Wait for the permission of the principal
B.Complete the attendance register first
C.Call medical help immediately
D.Ignore the student

A.46
B.45
C.44
D.43
Solution
Series — falling gaps
Differences: −21, −19, −17, −15 — each gap shrinks by 2.
So the next gap is −13.
58 − 13.
= 45 — option (b).
22
Statements:
No table is a chair.
Some chairs are wood.
Conclusions:
I. Some wood is not table.
II. Some chairs are not table.
A.Only Conclusion I follows
B.Only Conclusion II follows
C.Neither I nor II follows
D.Both I and II follow
Solution
Syllogism
No table is a chair, so every chair lies outside the table group — II follows.
Some chairs are wood; those wooden chairs are also outside the table group.
So some wood is definitely not table — I follows too.
Hence Both — option (d).
23

4 + 24 − 3 = 25 ✓ — it matches the right-hand side.
Hence − and × — option (d).
Replace the symbols: 36 − 12 × 4 + 6 ÷ 8 becomes 36 + 12 ÷ 4 − 6 × 8.
BODMAS: 12 ÷ 4 = 3 and 6 × 8 = 48.
36 + 3 − 48 = 39 − 48.
= −9 — option (b).
P, Q and R are siblings.
R is the son of W, so all three are W’s children.
P is female, hence W’s daughter.
Option (a).
W has two sons, X and Z, so X and Z are brothers.
Y is the child of X.
A father’s brother is an uncle.
Z is Y’s uncle — option (c).
Rule: a $ b = (a + b)².
(4+6)² = 100 ✓, (7+5)² = 144 ✓, (3+2)² = 25 ✓.
But (2+4)² = 36, not 42 ✗.
Hence option (a).
Some erasers are sharp and all sharp objects are pointed, so those erasers are pointed — I follows.
Pencils lie inside the eraser group, but nothing puts them inside the SHARP part of it.
So II is not certain.
Hence Only I — option (a).
INVESTIGATE has the letters I, N, V, E, S, T, I, G, A, T, E.
GIVE, GATE and SAVING can all be built from these ✓.
TEAMS needs the letter M, which is not present ✗.
Hence option (b).
MOPUTERC is simply a jumbled form of the word COMPUTER.
So the second term is the meaningful word hidden in the first.
The letters R, E, T, N, I, G, A, L rearrange to INTEGRAL.
Hence option (d).
Every letter moves +1: H+1 = I, K+1 = L, U+1 = V, J+1 = K.
Apply to YQTO: Y+1 = Z, Q+1 = R.
T+1 = U, O+1 = P.
Hence ZRUP — option (a).
1st letters: F, I, L — each +3 ⇒ next is O.
2nd letters: T, R, P — each −2 ⇒ next is N.
3rd letters: X, V, T — each −2 ⇒ next is R.
Hence ONR — option (b).
Income tax, GST and service tax are all levied by the CENTRAL government.
Property tax is collected by local bodies — municipalities and panchayats.
So it belongs to a different level of government.
Hence option (d).
Within each group the letters rise by 2: D, F, H, J.
From one group to the next every letter also moves +2.
H, J, L, N → J, L, N, P.
Hence JLNP — option (b).
10 machines make 10 boxes in 10 minutes, so ONE machine makes ONE box in 10 minutes.
Each machine works independently on its own box.
So 100 machines making 100 boxes still need only 10 minutes.
Hence option (a).
Replace the symbols: 190 − 80 ÷ 4 + 16 × 3.
BODMAS: 80 ÷ 4 = 20 and 16 × 3 = 48.
190 − 20 + 48.
