Question

in exam of total 500 marks, A got 10% less than B, B got 25% more than C & C got 20% less than D, if A got 360, what % did D get? ( options- 60%,70%,80%,90%)

Answer 1

the answer is 80%
hope this is the ri8 answer

A = 360 marks
A = B(1 - 10/100)
thus B gets 400 marks
B = C(1+25/100)
thus C gets 320
C = D(1 - 20/100)
thus D gets 400
% of D = (400/500)× 100
80%
