Question

If the ratio of Arun's weight to Vinay's weight is 6 : 11 and Arun's weight = 30 kg, then find Vinay's weight.

• A. 45 kg
• B. 55 kg
• C. 25 kg
• D. 66 kg

Answer 1

The correct option is B

55 kg

$\frac{\text{Ratio of Arun's weight}}{\text{Ratio of Vinay's Weight}}$ = $\frac{\text{Arun's Weight}}{\text{Vinay's Weight}}$

Given $\frac{\text{Ratio of Arun's weight}}{\text{Ratio of Vinay's Weight}}$ = $\frac{6}{11}$ and Arun's Weight = 30 kg

Hence $\frac{6}{11}$ = $\frac{30}{\text{Vinay's Weight}}$

$\Rightarrow$Vinay's Weight = $\frac{11\times 30}{6}$ = 55 kg
