Average weight of three boys P, T R is \( \large 54 \frac{1}{3} kg\), while the average weight of three boys T, F and G is 53 kg. What is the average weight of P, T, R, F and G?
|
A) 53.8 kg |
|
B) 52.4kg |
|
C) 53.2 kg |
|
D) Cannot be determined |
Correct Answer:
| D) Cannot be determined |
Description for Correct answer:
According to the question,
\( \large\frac{P + T + R}{3} = 54\frac{1}{3}\)
= > P + T + R = \( \large\frac{163}{3} \times 3 \)
= > P + T + R = 163
Also, \( \large\frac{T + F + G}{3} = 53 \)
= > T + G + F = 159
Clearly from the two equation, the problem cannot be solved.
