Answer 2

Answer:

15

Step-by-step explanation:

Let the Present age of Rachit be X.

His age 4 years ago= x-4

his age after 18 years= x+18

So., According to question..

x+18= 3(x-4)

Solving this linear equation, we get

x+18= 3x-12,

2x= 18+12=30

x=30÷2=15

So. Rachit's present age will be 15 years.
