Question

My sisters age is greater than 40 but less than 50. Her age is divisible by 2, 4, 8, and 12. How old is my sister?

Answer 1

Answer:

48

Step-by-step explanation:

48 is divisble by all of them

Answer 2

LCM of the given number is 24, and we know that age of your sister lies between 40 and 50, so the number divisible by 24 and lying in the given range is your sister's age,

that is 48

( because 48 is only number between 40 and 50 which is divisible by 24 )
