Question

P gets 360 marks out of a total score of 500. Marks of P are 10% less than Q's score. Q got 25% more than R, and R got 20% less than S. What is the percentage marks of S?

• A. 68%
• B. 80%
• C. 75%
• D. 72%

Answer 1

Answer:

B. 80%

P's score = 360

Q's score = 360 x (100/90) = 400

R's score = 400 x (100/125) = 320

S's score = 320 x (100/80) = 400

Percentage of S's marks = (400/500) x 100 = 80%
