Is that 5% or 15%
I dont really understand...where did you get the 20 from? And is it 5% or 15%
75% divide 15 is 5%. 45 is equivalent to 75%.. To get 5%, you have to divide 45 by 15 too which will give you 3. To find the total marks, you will just multiply it by 20 because 100% ÷ 5% is 20... so 3 x 20 will give you 60 which is the total marks.
An easier way is to just take 45 ÷ 0.75 which will give you 60.

75÷15 = 3
100÷5=20
100÷5=20
