Question

Five years ago, Sagar was twice as old as Tiru. Ten years later Sagar's age will be ten years more than Tiru's age. Find their present ages. What was the age of Sagar when Tiru was born. Solve it graphically.​

Answer 1

Answer:

The present age of Sagar is 25 years old while Tiru is 15 years old. Sagar was 10 years old when Tiru was born.

Step-by-step explanation:

We can start by making a table of their ages:

Let S be the age of Sagar

Let T be the age of Tiru

                          5 years ago  10 years later

S (Sagar’s Age) S-5 = 2 (T-5) (S-5)+10 = 10 + (T+5)

T (Tiru’s Age)          T-5           (T-5)+ 10

Solve for T using (S-5) + 10 = 10 + (T +5)

Substitute (S-5) with 2(T-5), therefore 2(T-5) + 10 = 10 + (T+5)

2T-10 +10=10+T+5

2T-T=15

T is 15 years old. Therefore Tiru is 15 years old. Since Sagar is 10 years older than Tiru then Sagar is 25 years old.
