Question:

30% of the men are more than 25 years old and 80% of the men are less than or equal to 50 years old. 20% of all men play football. 20% of the men above the age of 50 play football, what percent of the football players are less than or equal to 50 years?

C)

80%

D)

70%

Solution:

Ans: (c)

20% of the men are above the age of 50 years. 20% of these men play football. Therefore, 20% of 20 = 4% of the total men are football players above the age of 50 years. Because 20% of the men are football players. 16% of the men are football players below the age of 50 years. Therefore, the required % =  1620×100    = 80%
