Question 1

If 5 * 4 = 19, 7 * 3 = 22, then 6 * 5 = ?

Accepted Answer

Correct answer: A. 29 — This is a pattern-recognition problem where we must discover the hidden operation rule connecting the inputs and outputs. **Step 1: Analyze the first given equation** For 5 * 4 = 19 , test different operations: 5 	imes 4 = 20 \quad 	ext{(close to 19)} 5 	imes 4 - 1 = 19 \quad \checkmark **Step 2: Verify the pattern with the second equation** For 7 * 3 = 22 , apply the same rule: 7 	imes 3 - 1 = 21 - 1 = 20 \quad 	ext{(doesn't match 22)} So the rule is not simply a 	imes b - 1 . Let's try: a 	imes b + (a - b) 5 	imes 4 + (5 - 4) = 20 + 1 = 21 \quad 	ext{(doesn't match)} Let's try: a 	imes b + (a + b) 5 	imes 4 + (5 + 4) = 20 + 9 = 29 \quad 	ext{(doesn't match 19)} **Step 3: Test alternating patterns** Actually, let me reconsider. For 5 * 4 = 19 : (5 	imes 4) - 1 = 19 \quad \checkmark For 7 * 3 = 22 : (7 	imes 3) + 1 = 21 + 1 = 22 \quad \checkmark The pattern alternates: subtract 1 when the first number is odd and second is even, add 1 when the first number is odd and second is odd. **Step 4: Apply the rule to 6 * 5 = ? ** Since 6 is even and 5 is

Question 4

If a clock shows 3:15, what is the angle between the hour and minute hands?

Accepted Answer

Correct answer: B. 7.5° — Minute hand at 3 (90°). Hour hand moves 0.5° per minute, so at 15 min: 90 + 7.5 = 97.5°. Difference = 97.5 - 90 = 7.5°

Answer

A. 0°

Answer

C. 15°

Answer

D. 30°

Question 5

A train 150 m long passes a pole in 15 seconds. What is its speed in km/h?

Correct answer: A. 36 km/h — Speed = 150/15 = 10 m/s = 10 × 3.6 = 36 km/h

Answer

B. 40 km/h

Answer

C. 50 km/h

Answer

D. 45 km/h

Question 6

If 12 men can complete a work in 9 days, in how many days can 18 men complete the same work?

Accepted Answer

Correct answer: B. 6 days — Total work = 12 × 9 = 108 man-days. With 18 men: 108/18 = 6 days

Answer

Question 7

A is 5 years older than B. B is 3 years younger than C. If the sum of their ages is 35, what is A's age?

Accepted Answer

Correct answer: C. 14 years — Let B = x. Then A = x+5, C = x+3. (x+5) + x + (x+3) = 35. 3x + 8 = 35. x = 9. A = 14 years
