Question

Two numbers are in the ratio 3:4 and their sum is 91.Find the numbers

Answer 1

The sum of the ratio of the two numbers = 3+4 =7

sum of the numbers = 91

Then Number 1 = (3/7) * 91 = 39

Number 2 = (4/7) * 91 = 52

Ans. 39 and 52


2nd Method

the ratio of the numbers are 3: 4

So, let the numbers be 3x and 4x

By question,

3x + 4x = 91

⇒ 7x = 91

⇒ x = 91/7 = 13

⇒ 3x=3 * 13 = 39 and 4x = 4*13 = 52

Ans. 39 and 52
