In a school every student is assigned a unique identification number. A student is a football player if and only if the identification number is divisible by 4, whereas a student is a cricketer if and only if the identification number is divisible by 6. If every number from 1 to 100 is assigned to a student, then how many of them play cricket as well as football?
If a student plays cricket as well as football, then identification number must be divisible by both 4 and 6.
LCM of (4, 6) = 12
There are 8 multiples of 12 between 1 and 100.
The correct option is B.
