Question 36

Fill in the blanks to make the statements true.

20 m : 70 m = Rs. 8 : Rs. ___.

Answer 1

Given, 20 m : 70 m = Rs. 8 : Rs ___

$\frac{20m}{70m}=\frac{Rs.8}{x\left(let\right)}\Rightarrow \frac{20}{70}=\frac{8}{x}$

$\Rightarrow 20\times x=70\times 8$ [by cross multiplication]
$\Rightarrow x=\frac{70\times 8}{20}=28$
$\therefore$ 20 m : 70 m = Rs. 8 : Rs. 28
