Question

Priya weighs 60 kg, while her brother's weight is one-third of her weight. How much does he weigh?

• A. 50 kg
• B. 40 kg
• C. 25 kg
• D. 20 kg

Answer 1

The correct option is D 20 kg

Priya weights 60 kg and her brother's weight is ${\frac{1}{3}}^{\text{rd}}$ of her weight.

But, $\frac{1}{3}\times 60\text{kg}=20\text{kg}.$

Therefore, her brother weighs 20 kg.
