Question

Five years ago Pintu age was 18 then after 15 years from today Pintu age will be?​

Answer 1

Step-by-step explanation:

Let Rahul’s age be x years, and Rohan’s age be y years

Then,

x = y + 15

x - y = 15 … (i)

(x - 5) = 3(y - 5)

x - 5 = 3y - 15

x - 3y = -10 … (ii)

Subtracting (ii) from (i)

x - y - x + 3y = 15 + 10

2y = 25

y = 12.5

Substituting y = 12.5 in (i)

x - 12.5 = 15

x = 27.5

Therefore, Rahul is 27 and a half years old.
