Answer 1

Explanation:

Given, Soman has 20 stamps more than the number of stamps Raju has.

Both of them together have 140 stamps,

We need to find how many stamps does Raju have?

Let the number of stamps with raju be "x"

Then, number of stamps with soman becomes "140 – x"

Now according to given information,

number of stamps with soman – number of stamps with raju = 20

(140 – x) – x = 20

140 – 2x = 20

2x = 140 – 20 = 120

x = 60

Hence, raju has 60 stamps.
