Richa spends 1/4 of pocket money on chocolates,1/8 on pencils.At the end she had R's 40 left. How much did she have at the beginning?
Many solved 25 questions of his math assignment.This was 1/8 of total questions. He does not know 1/5 of the rest. How many questions were there in all? How many did he not know?
started with x
amount spent = (1/4)x + (1/8)x
= (3/8)x
leaving her with (5/8)x
5x/8 = 40
5x = 320
x = 64
Follow the same kind of reasoning for the 2nd question.
Let me know what you did.
1/4 on chocolate
2/5 on pencils.
1/4+2/5= 3/8 .
