Question

Average weight of three boys P, T and R is $54\frac{1}{3}kg$, while the average weight of three boys T, F and G is 53 kg. What is the average weight of T, R, F and H?

• A. 53.8 kg
• B. 52.4 kg
• C. 53.2 kg
• D. Data inadequate
• E. None of these

Answer 1

The correct option is D Data inadequate

Here, average weight of P, T and R = $=54\frac{1}{3}kg$
$\therefore$ Total weight of P, T and R $=3\times \frac{163}{3}$
= 163 kg
Again, total weight of T, F and G = 3 $\times$ 53
= 159 kg
Further, it can't be solved, so data is inadequate.
