Question

Two numbers are in the ratio of 8 : 3. If they differ by 15, then find the numbers.

• A. 35, 20
• B. 24, 9
• C. 16, 1
• D. 17, 2

Answer 1

The correct option is B

24, 9

The numbers are in the ratio 8:3.

Let the first number be 8x and let the second number be 3x.

Given that they differ by 15.

$\therefore 8x-3x=15$

$5x=15$

$x=3$.

First Number $=8x=8\times 3=24$

Second Number $=3x=3\times 3=9$
