Question

Find the value of digit z if 12z4 divisible by 4

Answer 1

Answer:

2,4,6or8

Step-by-step explanation:

according to the divisiblity rule of 4 any no. is divisible by 4 if its last 2 digits are divisible by 4

so, 24 , 44 , 64 and 84 are the no.s divible by so the values can be 2 , 4 , 6 , 8 but the greatest value can be 8 and smallest can be 2

Answer 2

Answer:

The answer will be 0 or 2 or 4 or 6 or 8

Given problem:

Find the value of digit z if 12z4 divisible by 4

Step-by-step explanation:

given number 12z4  is divisible by 4

Note: The divisibility rule of 4 states that if a number divisible by 4 then the number formed by last digits of that particular given number is also divisible by 4  

Example:   1124 is divisible by 4 here the number formed by last two digits 24 is also divisible by 4.    

Therefore in given number 12z4 , z4 must be a number which will divisible by 4  

if z = 2  then 24 is divisible by 4

  z = 4 then  44 is divisible by 4

  z = 6 then 64 is divisible by 4

  z = 8 then 84 is divisible by 4

  z = 0 then 04 is also divisible by 4

  ∴ the value of z will be 0 or 2 or 4 or 6 or 8
