Answer 1

Answer:

Reema is 4 years old. Her cousin is 28 years old.

Step-by-step explanation:

Let Reema's present age be 'x'

Therefore, Reema's cousin's present age = 7x years

3(x + 8) = 7x + 8

3x + 24 = 7x + 8

24 - 8 = 7x - 3x  (Transposing method)

16 = 4x

x = 16/4

x = 4 (Reema's age)

Reema's cousin's age = 7x

                                     = 7 * 4

                                     = 28 years

Therefore Reema is 4 years old and her cousin is 28 years old.
