NCERT Solutions for Class 8 Maths Chapter 2 Linear Equations in One Variable Exercise 2.3

Examples From Chapter 2 Linear Equations in One Variable

Ex. 1 If Hari's father gave him Rs 70, he now has Rs 130. How much money did Hari have in the beginning?

Soln: Let, the amount Hari had initially be = Rs x
Then,

The money his father gave him = Rs 70
So, x + 70 = 130
∴ x = 130 - 70
x = 60
So, Hari had Rs 60 initially.

Ex. 2 If five times Raju' pocket money is Rs 80. What is his pocket money?
