Question

If 7 is added to a ratio, it becomes 3 : 5. Find the ratio.

​

Answer 1

let the two numbers be 3x and 5x..

therefore, according to the question..

3x+7/5x+7 = 11/16

using cross multiplication.

16(3x+7) = 11( 5x + 7)

48x + 16*7 = 55x + 11*7

16*7 - 11*7 = 55x - 48x

7(16-11) = 7x

x = 5

therefore, the two numbers are

3x = 3*5 = 15

5x = 5*5 = 25
