The question was asked by my college professor while I was bunking the class.

This key question is from Age/Money/Denomination of Currency Word Problems in chapter Linear Equations in One Variable of Mathematics – Class 8

Answer 1

The correct option is (a) 56 years

To explain: The present age of Rahul and Rajiv is 27 and 19 respectively, after five years their age will be Rahul’s age =(27+5)years and Rajiv’s age = (19+5)years.

Sum of Rahul’s age and Rajiv’s age = (27+5)+(19+5)

∴ Sum of Rahul’s age and Rajiv’s age = 32+24

∴ Sum of Rahul’s age and Rajiv’s age = 56 years.
