Question

Mayank is $1\frac{2}{5}$ times as tall as vansh. If Mayak is 38 cm taller then Vansh, what is Mayank's height

• A. $133cm$
• B. $123cm$
• C. $95cm$
• D. $129cm$

Answer 1

The correct option is A $133cm$

Let height of vansh$=x$

then height of Mayank$=1.\frac{2}{5}x$

$=\frac{7}{5}x$

$38cm=\frac{7}{5}x-x$

$38=\frac{2}{5}x$

$\Rightarrow x=95cm$

Height of Mayank$=\frac{7}{5}x$

$=\frac{7}{5}\times 95$

$=133$cm.
