Answer 1

Step-by-step explanation:

Out of a certain sum of money a boy spends 3/5 and then 1/4 of the remainder. He has Rs 15 left,

amount he had he at first = Rs 50

let say boys has money = Rs 20 M

Boy spends money = (3/5) * 20 M = 12 M

Remainder Money = 20 M - 12 M = 8 M

He spend then 1/4 of remainder

Further spend = (1/4) 8 M = 2 M Rs

He left with money = 8 M - 2 M = 6 M Rs

6 M = 15 M

=> M = 2.5

20 M = 20 * 2.5 = Rs 50

He had rs 50 amount at first
