Ratio of Present age = 7:9

Ratio after 4 years = 4:5 = 8:10

Now, look at the difference between numerator & denominator in both ratios. It is 2 in both cases.

Take difference of numerators of both ratios & denominators of both ratios. It is 1 in both cases.

=> For a gap of 1 year, present ages would be 7 & 9.

If gap is 4 years, present ages would be 7x4 & 9x4

=> 28 & 36 years

Ratio of Present age = 7:9

Ratio of Present age = 7:9Ratio after 4 years = 4:5 = 8:10

Ratio of Present age = 7:9Ratio after 4 years = 4:5 = 8:10Now, look at the difference between numerator & denominator in both ratios. It is 2 in both cases.
