Question

A and B were able to solve section A and section B respectively in a paper containing only two sections. If A can complete 6 questions in an hour whereas B is 50% more efficient than A, how many questions were given in the exam if the exam duration is 3 hours?

• A. 40
• B. 45
• C. 50
• D. 65

Answer 1

The correct option is B

45

Number of questions solved by A in an hour = 6

Number of questions solved by A in 3 hours = 18

Number of questions solved by B in 3 hours = $18\times 1.5=27$

Total number of questions = 45
