Question

Harry solved 25 questions of his Maths assignment . This was 1/8 of the total questions . He does not know 1/5 of the rest . How many questions were there in all? How many questions did he not know?​

Answer 1

Answer:

let the total questions be X

A/Q

X/8=25

=X=25*8=200

total questions are 200, solved questions=25

rest questions=200-25=175

questions he does not know=1/5 of 175

=1/5*175

=35
