Question

Two numbers are in the ratio $7:2$. If their sum is $54$, find the numbers.

Answer 1

Given that,

Ratio of two numbers $=7:2$

Let, the numbers are $7x,2x$

$\because 7x+2x=54$

$9x=54$

$x=\frac{54}{9}=6$

$7x=7\times 6=42$

$2x=2\times 6=12$

$\therefore$ The numbers are $42,12$ respectively.
