What is the average weight (in kg) of A, B, C, D, E, F 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. \frac{201}{7} ✓
- B. \frac{197}{7}
- C. 30
- D. 32
Correct Answer: A. \frac{201}{7}
Explanation
The weights are calculated as: A=15, B=25, C=25, D=40, E=36, F=32, G=28. Total weight = 15+25+25+40+36+32+28 = 201. The average weight is \frac{201}{7} kg.
