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?  Pick one:
A) 60%
B) 70%
C) 80%
D) 90%
E) 100%
Explanation :   Let total number of men = 100   Then   80 men are less than or equal to 50 years old   (Since 80% of the men are less than or equal to 50 years old)   =&gt; 20 men are above 50 years old (Since we assumed total number of men as 100)   20% of the men above the age of 50 play football   ⇒Number of men above the age of 50 who play football = 20× (20/100) = 4   Number of men who play football = 20 (Since 20% of all men play football)   Percentage of men who play football above the age of 50 = (4/20) × 100=20%   =&gt;Percentage of men who play football less than or equal to the age 50 = 100%−20%=80%   ANSWER IS 80%
