Question

Answer 1

Answer:

Amount he had at first = 50

Step-by-step explanation:

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

Let say boy had Amount = 20 M

Amount Spend = (3/5) * 20M = 12M

Remainder Amount = 20M - 12M = 8M

1/4 of remainder is spent = (1/4) * 8M = 2M

Final amount Left = 8M - 2M = 6M

6M = 15

=> M = 5/2

20M = 20(5/2)

=> 20M = 50
