Question

Two numbers are in the ratio 4:5. If 7 is subtracted from each of them, then the ratio becomes
3.4. Find the numbers,​

Answer 1

Answer:

Nos. 4x and 5x

7 is subtracted, 4x-7 and 5x-7

4x-.7/5x-7=3/4

4(4x-7)=3(5x-7)

16x-28 = 15x-21

16x-15x=-21+28

x = 7

Nos. 4x = 28

5x=35

Nos are 28 and 35
