- A. 161
- B. 101
- C. 175
- D. 129
Answer: Option B

175 = 5² × 7, 161 = 7 × 23, 129 = 3 × 43. 101 has no factor other than 1 and itself, so it is prime.
If a : b = 4 : 5, b : c = 5 : 4 and c : d = 6 : 5, then a : b : c : d =
- A. 12 : 16 : 12 : 10
- B. 10 : 15 : 10 : 12
- C. 12 : 15 : 12 : 10
- D. 12 : 15 : 10 : 12
Answer: Option C
Explanation:
a : b : c = 4 : 5 : 4. Make c = 12 → a : b : c = 12 : 15 : 12. c : d = 6 : 5 = 12 : 10. So a : b : c : d = 12 : 15 : 12 : 10.
