Question

6. Two numbers are such that the ratio between them is 5 : 2. If each is

increased by 1 the ratio between the new numbers so formed is 7 : 3. Find
the original number.

Answer 1

Answer:

let the no.s be 5x and 2x

if 1 is added to the no.s

than no.s are=5x+1 and 2x+1

according to the question;

5x+1/2x+1=7/3

3(5x+1)=7(2x+1)

15x+3=14x+7

15x-14x=7-3

x=4

5x=20and

2x=8
