Question

The ratio between two numbers is 15:7. If each number be decreased by 2 the ratio becomes 7:3.Find the number??

Answer 1

Answer:

The answer is 30 and 14.

Step-by-step explanation:

15x- 2÷ 7x-2 = 7/3

Now cross multiply

(15x- 2)3= 7( 7x-2)

45x - 6 = 49x - 14

49x - 45x = 14 - 6

4x = 8

x = 8/4

X = 3

Hence the numbers are...

15 x 2 =30

And  

7 x 2= 14

Hence the numbers are 30 and 14.
