Answer 2

Answer:

Lakshmi = 20 years old, Riya = 28 years old

Step-by-step explanation:

Current ratio:

Lakshmi : Riya = 5 : 7

4 years later:

Lakshmi : Riya = 5x  + 4 : 7x + 4

Given that the sum of their age will be 56:

(5x + 4) + (7x + 4) = 56

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 48

x = 4

Find their present age:

Lakshmi = 5x = 5 x 4 = 20

Riya = 7x = 7 x 4 = 28

Answer: Lakshmi = 20 years old, Riya = 28 years old
