Question

for what value of x, a number of the form (x ×100+6×10+8) is divisible by 3​

Answer 1

Answer:

when a number is divisible by 3 then the sum of the digits is also divisible by 3

here the digits are x,6 and 8

so, x+6+8=14+x

if x=1 then sum is 15 which is divisible by 3

if x=4 then sum is 18 which is divisible by 3

if x=7 then sum is 21 which is divisible by 3

so the values of x are 1 , 4 , 7
