Solution

The correct option is A
15/14

Ratio of the boy’s height to the girl’s height is (150 cm/1.4 m). To compare two similar quantities using ratio, we must make sure that their units are same. We know that,

1 m = 100 cm

$\Rightarrow$ 1.4 m = 140 cm

The ratio hence becomes equal to $\frac{150 c m}{140 c m}$ i.e. $\frac{15}{14}$ .
