Question

kumar is x years old. Kumar's uncle is now four times as old as Kumar will be in 5 years' time. Find the expression to represent the age of Kumar's uncle now.

Answer 1

Answer:

Khairul age=X

Khairul's age after 5yers=X+5

As per question, Khairul's uncle age will be 4times the age of khairul after 5 years.

Therefore Khairul's uncle age after 5years=4(X+5)=4X+20

Therefore Khairuls uncle present age = 4X+20-5= 4X+15
