Quantitative
A can do a piece of work in 10 days and B in 15 days. Days to finish together:
1/10 + 1/15 = 1/6 → 6 days.
Verbal
Fill in: The news _____ shocking.
News is singular → is.
Quantitative
A and B can complete a work in 12 days, B and C in 15 days, C and A in 20 days. In how many days will A alone complete the work?
Let total work = LCM of 12, 15, 20 = 60 units A + B efficiency = 60/12 = 5 units/day B + C efficiency = 60/15 = 4 units/day C + A efficiency = 60/20 = 3 units/day Adding all: 2(A + B + C) = 5 + 4 + 3 = 12 units/day A + B + C = 6 units/day A's efficiency = (A +
Quantitative
Divide ₹720 in the ratio 2:3. The larger share is:
Larger = 3/5 × 720 = ₹432.
Reasoning
If every letter is shifted +2 in the alphabet, CODE becomes:
Each letter +2 → EQFG.
Quantitative
Find compound interest on ₹10,000 for 2 years at 10% per annum, compounded annually.
Amount = P(1 + R/100)^n Amount = 10000(1 + 10/100)^2 = 10000 × 1.1^2 = 10000 × 1.21 = ₹12,100 CI = Amount - Principal = 12100 - 10000 = ₹2,100
Verbal
Find antonym of "Temporary"
Correct answer: Permanent
Reasoning
Which comes next: 5, 10, 20, 40, ?
Each term doubles → 80.
Quantitative
A sum doubles in 5 years at simple interest. The rate of interest is:
For doubling, RT = 100 → R = 100/5 = 20%.
Verbal
Problem: Find the synonym of "ABUNDANT": a) Scarce b) Plentiful c) Limited d) Rare

Verbal
A shopkeeper sells an article at a profit of 20%. If he had bought it at 20% less and sold it for ₹5 less, he would have gained 25%. Find the cost price of the article.
Let CP = 100 SP = 120 (20% profit) New CP = 80 (20% less) New SP = 120 - 5 = 115 New Profit = 115 - 80 = 35 New Profit % = (35/80) × 100 = 43.75% But given new profit is 25%, so: Let actual CP = x Actual SP = 1.2x New CP = 0.8x New SP = 1.2x - 5 New Profit = (
Reasoning
Find the next number: 8, 6, 9, 7, 10, ?
−2,+3 alternating → 10-2=8 → 8.
Quantitative
Identify the error: "Neither of the students were present in the class."
Correct answer: "were" should be "was"
Reasoning
In each question a set of six statements is given. Identify the answer choice in which the statements are logically related. A: All green is blue B: All green is white C: All green is black D: All black is white E: All blue is yellow F: All blue is white
Correct answer: ABF
Reasoning
