Best Answer Explained in Below-:

Let's call the number of marbles Rahim has

x

The number of marbles Amin has is 80% of Rahim's collection which is

0.8 x

We are given that Rahim has 80 more marbles than Amin Rahim's collection - Amin's collection = 80 -->

x - 0.8 x = 80

Solving the equation, we get

x = 400

The total number of marbles is the sum of the number of marbles Amin has and the number Rahim has which is

400 + 0.8 * 400 = 720

So the total number of marbles they have is 720.
