Question

If the ratio of ages of Mira and Lisa is 4:7. Four year later the sum of their ages will be 56 years. Find their present ages

Answer 1

Answer:

Let their present ages be 4x, 7x 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.
