What is the difference between the weights (in kg) of G and C?
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. 4
- B. 3 ✓
- C. 2
- D. 1
Correct Answer: B. 3
Explanation
D's age-weight ratio is 9:20 and age is 18, so D's weight is 40. G's weight is 40 - (3 \times 4) = 28. A's age-weight ratio is 2:5 and age is 6, so A's weight is 15. B's weight is 15 + 10 = 25, so C's weight is also 25. The difference is 28 - 25 = 3 kg.
