Answer : Option C

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)

=> 20 men are above 50 years old (Since we assumed total number of men as 100)

Number of men above the age of 50 who play football = 20

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 = 20 times 100 = 20%

=>Percentage of men who play football less than or equal to the age 50 = 100% - 20% = 80%
