Question

Maurice has completed 64 pages of the research paper he is writing. That is 80% of the required length of the paper. What is the required length of the paper?

Answer 1

80 pages

Explanation:

Let the required length of paper = x

Hence:

80% of x = 64 pages

80/100 × x = 64 pages

80x /100 = 64 pages

Cross Multiply

80x = 100 × 64 pages

x = 6400/80

x = 80 pages

Therefore, the required length of the paper = 80 pages
