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. If 20% of the men above the age of 50 play football, what percentage of the football players are less than or equal to 50 years?  Select: A) 15% B) 20% C) 80% D) 70% E) 90%
Explanation :   Let number of men = 100.   Then, 80 men are less than or equal to 50 years old i.e 20 men are greater than 50 years of age.   Now, the number of men above 50 years who play football = 20% of 20 = 4.   20% of all men play football i.e total no. of men who play football = 20, out of which 4 men are above 50 years old.   So, 20 - 4 = 16 men are less than or equal to 50 years old.   Therefore, percentage of football players less than or equal to 50 years = (16/20) x 100 = 80% .   Answer : 80%
