• A. 85 kg
• B. 85.11 kg
• C. 85.20 kg
• D. 85.15 kg

Answer 1

The correct option is B 85.11 kg

Weight of Boy=$56.74kg$

Given that his father is $1.5$ times heavier than his son.

so, weight of father=$1.5\times 56.74$

$=\frac{15}{10}$$\times$ $\frac{5674}{100}=$ $\frac{85110}{1000}=85.110=85.11kg$
