Question

7) Two numbers are in ratio 4:5.
if 20 is subtracted from both then ratio becomes 3:4. Find numbers​

Answer 1

Answer:

Let the numbers be 4x and 5x

20 subtracted from both the numbers;

4x-20

5x-20

According to the problem;

4x-20/5x-20=3/4

4(4x-20)=3(5x20)

16x-80=15x-60

16x-15x= -60+80

x=20

The numbers-

4x=4*20=80

5x=5*20=100
