A number when divided by 5 leaves remainder 3. What is remainder when twice the number is divided by 5?
n = 5k+3 → 2n = 10k+6 = 5(2k+1)+1 → remainder 1.
Reasoning
Find the next number in the series: 2, 6, 12, 20, 30, ?
Pattern analysis: - 2 = 1 × 2 - 6 = 2 × 3 - 12 = 3 × 4 - 20 = 4 × 5 - 30 = 5 × 6 Next term = 6 × 7 = 42
Quantitative
A 120 m train crosses a pole in 8 s. Speed in km/h is:
Speed = 120/8 = 15 m/s = 54 km/h.
Reasoning
Two trains move in the same direction at 50 kmph and 32 kmph respectively. A man in the slower train observes that 15 seconds elapse before the faster train completely passes by him. What is the length of the faster train?
Relative speed = 50 - 32 = 18 kmph = 18 × 5/18 = 5 m/s Time = 15 seconds Length of faster train = Relative speed × Time = 5 × 15 = 75 meters
Reasoning
Statements: All engineers are professionals. Some professionals are managers. Conclusions: I. Some engineers are managers. II. All managers are engineers.
Analyzing the statements: - All engineers are professionals (A → B) - Some professionals are managers (B → C, some) Conclusion I: Some engineers are managers - Since all engineers are professionals, and some professionals are managers, we can say some engineer
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

Each letter +2 → RGP.
Verbal
A trader sells an article at a profit of 25%. If he had bought it at 10% less and sold it for ₹15 less, he would have gained 30%. Find the cost price of the article.
Let actual CP = x Actual SP = 1.25x (25% profit) New CP = 0.9x (10% less) New SP = 1.25x - 15 New Profit = (1.25x - 15) - 0.9x = 0.35x - 15 New Profit % = ((0.35x - 15)/0.9x) × 100 = 30 (0.35x - 15)/0.9x = 0.30 0.35x - 15 = 0.27x 0.08x = 15 x = ₹187.50
Verbal
One who loves books is a:
Bibliophile = lover of books.
Quantitative
If 20% of a number is 48, the number is:
Number = 48 × 100/20 = 240.

Correct answer: Kind
Reasoning
Which of the following is the next term in the series: 2, 6, 12, 20, 30, ?
Pattern: Differences are 4, 6, 8, 10 (consecutive even numbers) Next difference = 12 Next term = 30 + 12 = 42 Alternative pattern: n(n+1) where n starts from 1 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, 6×7=42
Quantitative
Two numbers are in ratio 3:5 and their sum is 56. The larger number is:
