Answer 1

Answer:

3600

Step-by-step explanation:

Let x denote the amount of money Jay and Rohan initially.

Jay gave 25% to Rohan,

Rohan's money = x + 0.25x = 1.25x

Rohan spent 50% on purchasing books,

Rohan's money = 1.25x - 0.5(1.25x) = 0.625x

Rohan is left with 4500,

Rohan's money = 4500

=> 0.625x = 4500

=> x = 4500/0.625

x = 7200

Amount spent on purchasing the books:

50% of x was spent on purchasing the books

So,

0.5 * x = 0.5 * 7200 = 3600
