General Intelligence & Reasoning
The Lucknow meeting was on 10 April.
Bengaluru came three days after it.
10 + 3.
= 13 April — option (b).
(a) writes Tower without the s; (c) misspells Pune as Puna.
(d) misspells Maharashtra as Maharastra.
Only (b) matches the sample exactly.
Hence option (b).
Each term falls by 6.
6 − 6 = 0, 0 − 6 = −6, −6 − 6 = −12 ✓.
−12 − 6 = −18, and −18 − 6 = −24 ✓.
= −18 — option (b).
Rule: a * b = a² + b.
Check: 4² + 3 = 19 ✓, 5² + 6 = 31 ✓, 7² + 4 = 53 ✓.
6² + 3 = 36 + 3.
= 39 — option (d).
G ≥ C and C = B, so G ≥ B — Conclusion I is TRUE.
A ≥ E ≥ B = C > D gives A > D — Conclusion II is TRUE as well.
The question asks which conclusion is FALSE, and neither of them is.
Neither I nor II — option (c).
Among the single digits, only 4, 6, 8 and 9 are composite.
0 and 1 are neither prime nor composite, and 2, 3, 5, 7 are prime.
468 is made up of 4, 6 and 8 — all composite ✓.
Hence option (b).
Cow, lion and sheep are all MAMMALS.
A pigeon is a bird.
So it belongs to a different class of animals.
Hence option (b).
BAKE and BORE share B and E; their digit sets share 5 and 2. RICE and BORE share R and E; their sets share 9 and 2 ⇒ E = 2, B = 5, R = 9.
CALB and BAKE share A and B; their sets share 4 and 5 ⇒ A = 4. From BAKE the digit left is K = 3.
From RICE, I and C take 1 and 8; from CALB, C and L take 8 and 6 ⇒ C = 8, I = 1, L = 6; from BORE, O = 7.
So L K O = 6, 3, 7 — option (b).
GH becomes IJ when each letter moves +2.
Apply the same to MN: M+2 = O.
N+2 = P.
= OP — option (a).
27 = 3³ and 64 = 4³, so the rule is the cube of the next number.
125 = 5³.
So the answer is 6³.
= 216 — option (d).
Rule: cube the number, then add the number itself.
Check: 16³ = 4096 and 4096 + 16 = 4112 ✓.
14³ = 2744.
2744 + 14 = 2758 — option (a).
Encouraging public transport directly cuts the number of vehicles on the road — 1 follows.
Moving ALL industries and vehicles out of cities is extreme and impractical.
A course of action must be workable, not merely drastic.
Only 1 — option (a).
Wipro must be on a floor that is neither even nor prime: from 1 to 8 only 1 qualifies, so Wipro is on floor 1.
HCL is on 7 and not adjacent to Vodafone, so Vodafone (even) is on 2 or 4; Flipkart is two above Jio with at least two floors above it, giving Jio 4 and Flipkart 6.
Vodafone therefore takes floor 2; Whatsapp and Chrome, one floor apart and away from HCL, take 3 and 5, leaving Amazon on 8.
The 1st floor holds Wipro — option (c).
Only SOME animals are mammals, and those may lie entirely outside the cat group — I is not certain.
"Some animals are mammals" never reverses into "all mammals are animals" — II is not certain either.
Both are possibilities, not conclusions.
Neither follows — option (d).
Some A are B and every B is C, so those A are certainly C — I follows.
All B lie inside C, and no C is D, so no B can be D — hence some B are certainly not D, and II follows.
Both come straight out of the chain.
Both follow — option (c).
The Taj Mahal, the Great Wall of China and the Leaning Tower of Pisa all figure among the wonders of the world.
The Eiffel Tower, though world-famous, is not counted among them.
So it stands apart from the rest.
Hence option (a).
First term a = 10 and common difference d = 15 − 10 = 5.
aₙ = a + (n − 1)d.
a₁₁ = 10 + 10 × 5.
= 60 — option (a).
1st letters: D, G, J, M — each +3 ⇒ next is P.
2nd letters: E, H, K, N — each +3 ⇒ next is Q.
So the pair is P and Q.
= PQ — option (c).
The rule alternates × 2 and − 2.
18×2 = 36, 36−2 = 34, 34×2 = 68, 68−2 = 66, 66×2 = 132 ✓.
Next comes a −2 step: 132 − 2.
= 130 — option (a).
Every letter moves +1: C+1 = D, A+1 = B, T+1 = U.
Apply to MAT: M+1 = N.
A+1 = B, T+1 = U.
= NBU — option (a).
1st letters: N, O, P, Q — each +1 ⇒ next is R.
2nd letters: R, S, T, U — each +1 ⇒ next is V.
So the pair is R and V.
= RV — option (c).
Lines 1 and 2 share "apple" and "bird" with codes pqr and vwx; lines 2 and 3 share "fish" ⇒ fish = yz.
Lines 1 and 3 share "banana" ⇒ banana = stu, so from line 1 apple and bird take pqr and vwx.
Line 2 has bird = vwx left over, giving apple = pqr.
So apple fish banana = pqr, yz, stu — option (a).
A principal must apply the same rules to every student alike.
The decision should rest on the school’s rules and the evidence on record.
Yielding to influence or to sentiment would be unfair to the other students.
Hence option (c).
The sum of the first n odd numbers is always n².
Here n = 25.
25² = 625.
So his answer is correct — option (a).
Every letter moves one step BACK: J−1 = I, U−1 = T, N−1 = M, G−1 = F, L−1 = K, E−1 = D.
Apply to FISH: F−1 = E, I−1 = H.
S−1 = R, H−1 = G.
= EHRG — option (a).Finished reading? Now test yourself.
The same 25 questions, but with a timer and the answers hidden — 15 minutes.
