The average weight of A, B and C is 52 kg. If the average weight of B and C is 44 kg and that of C and A is 46 kg, then what will be the weight of C?
Answer
The correct answer is B: 24 kg. A+B+C = 156, B+C = 88, C+A = 92. Adding B+C and C+A: B+2C+A = 180.
- A.68 kg
- B.24 kg✓ Correct
- C.36 kg
- D.38 kg
A+B+C = 156, B+C = 88, C+A = 92. Adding B+C and C+A: B+2C+A = 180. Since A+B+C = 156, C = 180–156 = 24 kg.
