In a class of 50 students, Raghu's rank is twice that of Paul. There are 10 students who have ranks worse than that of Raghu. Paul's rank in the class is

  • A.5th
  • B.10th
  • C.15th
  • D.20th

Answer: D

Paul's rank is 20th.

In a class of 50, if 10 students rank below Raghu, Raghu's rank is 50 - 10 = 40th. Raghu's rank is twice Paul's, so Paul's rank is 40/2 = 20th.

The other options come from misreading Raghu's rank: 10th or 5th would follow if Raghu were 20th or 10th, which ignores the 10 students ranked below him, and 15th fits no reading.
