Question

Three persons in proportions 4 is to 7 is to 9 8 years ago the sum of their ages was 56 find their present ages in years

Answer 1

Answer:

16 YEARS, 28 YEARS AND 36 YEARS

Step-by-step explanation:

Let their present ages be 4x, 7x and 9x years respectively.

Then, (4x - 8) + (7x - 8) + (9x - 8) = 56

20x = 80

x = 4.

Their present ages are 4x = 16 years, 7x = 28 years and 9x = 36 years respectively.
