To find:

The numbers

Given:

• A number is 4/5 times another number
• The sum of these two numbers is 70

Solution:

Let,The first number be x and the second number is ( $\frac{4}{5}$ * x)=$\frac{4x}{5}$

$\to \frac{4x}{5}$ + x = 70

$\to or, \frac{4x + 5x}{5}$ = 70

$\to or,\frac{9x}{5}$=70

$\to or, x=\frac{5 * 70}{9}$

$\to or, x=\frac{350}{9}$

Check:

$\to$The 1st number=($\frac{350}{9}$)=38.88 (approx)

$\to$The 2nd number=($\frac{4 * 350}{5 * 9}$)=31.11 (approx)
