Question

At Tanay’s birth, he was 34 years younger than his father. What will be his age after 20 years?

(a) 20

(b) 54

(c) 0

(d) 14

I got this question in final exam.

The query is from Applications of Linear Equation (Just Solving the Equations) topic in chapter Linear Equations in One Variable of Mathematics – Class 8

Answer 1

Right option is (a) 20

Best explanation: At birth Tanay’s age would be 0, at that time difference in ages was 34 years.

As the time passes Tanay and his father’s age increases but the difference remains same.

Hence, Tanay’s age would be

i.e. Age at his birth + 20 years

i.e. 0 + 20 years

i.e. 20 years.
