Question

riya is 3 times as old as her brother, Rohan. In 10 years, the sum of their ages will be 36. How old are they now?

Answer 1

Answer:

Rohan's age= 19, Riya's age= 37

Step-by-step explanation:

Let Rohan's age be 'x'

Riya's age = 3x

After 10 years,

Rohan's age = x + 10

Riya's age = 3x + 10

(3x + 10) + (x + 10) = 36

3x + 10 + x + 10 = 36

3x + x = 36 - 10 - 10

4x = 16

x = 16/4

x = 4

Rohan's present age = x + 10 = 4 + 10 = 14 years

Riya's present age = 3x + 10 = 3 × 4 + 10 = 22 years
