What is the average age (in years) of B, C, D, E and G?
Consider the following for the next (05) items that follow : A, B, C, D, E, F and G are cousins. D is thrice as old as A. Further, C is as many years younger to B, as G to E and E to D. The average age of D and G is 16 years; the average age of A and E is 11 years; the average age of B and C is also 11 years. B and C have equal weight. A's weight is 10 kg less than that of B; D is 4 kg heavier than E; E is 4 kg heavier than F; F is 4 kg heavier than G. Further, D has age-weight ratio of 9: 20, where age is in years and weight in kg; A has age-weight ratio of 2: 5. Moreover, none of them is more than 40 kg.
- A. 12
- B. 13
- C. 14 ✓
- D. 15
Correct Answer: C. 14
Explanation
Based on the age relations: D=18, E=16, G=14. For B and C, B+C=22 and B-C = D-E = 2, yielding B=12, C=10. Sum of their ages = 12+10+18+16+14 = 70. Average = \frac{70}{5} = 14 years.
