Solution

Answer :
Given ,
Younger brother’s height = 200 cm

Jason’s height = 10% more than his younger brother , So

Jason’s height = 200 + 10% of 200 = 200 + $\frac{200 \times 10}{100}$ = 200 + 20 = 220 cm ( Ans )

And

Jason’s height = 25 % more than that his elder brother
Let
Elder brother’s height = x

x + $\frac{25 x}{100}$ = 220

$\frac{5 x}{4}$ = 220

5x = 880

x = 176
So,
Height of Elder brother = 176 cm ( Ans )
