92. In a race, the first four winners are to be awarded points. Each winner’s points must be 5 more than that of the next position winner. Total sum of the points to be awarded is 50. What will be the points for the third position winner

Correct Answer: (c) 10
Solution:

Let the total points awarded to fourth place’s winner = x
Then, the total points awarded to third place’s winner = x + 5
the total points awarded to second place’s winner = x + 10
the total points awarded to first place’s winner = x + 15
According to the question,
x + x + 5 + x + 10 + x + 15 = 50
⇒ 4x = 50 − 30
∴ x = 5
Hence, the points for the third position winner are (5 + 5) = 10.
