Step-by-step explanation:

Since the boy has spent 3/4 of his money, he has 1/4 of his money with him. Out of this he gives 4/5 th. to her s sister. This means he has given 1/4x 4/5 = 1/5

Since the boy has spent 3/4 of his money, he has 1/4 of his money with him. Out of this he gives 4/5 th. to her s sister. This means he has given 1/4x 4/5 = 1/5He has already spent 3/4 of the money and given away 1/5 of the money to his sister. That means he has used up 3/4 + 1/5 = 19/20. So finally what remains with him is 1/20 and this is equal to 40₹. Thus, the original money he had with him is 40 x 20 which is 800₹
