Answer 1

Step-by-step explanation:

assume the total pocket to be x and then find the money spent then subtract the money spent from the total money now from the remaining money take out the money given to his sister then subtract the money given to his sister from the money left and the fraction which comes is equal to 40rs

then equalise them and find the value of x

Answer 2

Answer : 800

explanation:

suppose he has Rs. 100

3/4 spent

remained 1/4 of 100 = 25

4/5 of 25 given to sister

remained = 1/5 of 25 = 5

5≈40 (given)

1≈8

so 100≈800

that's the answer.
