if the number is divisible by 4 then the possible value of a can be one of

2 , 4 ,6, 8 or 0

because its rule that if two last digit of a numer is divisible by 4 then the number is also divisible by 4.

so 0,2,4,6,8 values of A make it divisible by 4.

Answer 2

hi

aim : If the number 7713A8 is divisible by 4, where A is a digit , what will be one of the possible value of A

so let us know divisiblility by 4

A number is divisible by 4 if the number's  last two digits are divisible by 4

so 7713A8

last 2 digit is A8

so A8 should be divisbilbe by 4

=>a = 0

hence the number is 771308
