Step-by-step explanation:

x = 1,4,7

Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.

24x5

If x = 1 , we get 2 + 4 + 1 + 5  = 12 {which is divisible by 3 }

If x = 4 , we get 2 + 4 + 4 + 5  = 15 {which is divisible by 3 }

If x = 7 , we get 2 + 4 + 7 + 5  = 18 {which is divisible by 3 }
