There are 14 digits of credit card number to be filled. Each of the below three boxes contains continuous digits of 18 as sum. Given: 4th digit is 7 and 7th digit is x. Then what is the value of x?

• a+b+c=18 and b+c+d=18
  given d=7 ,so b+c=11
  then we get b=5 and c=6
  c+d+e=18, so e=18-(c+d)=5
  since d+e+f=18
  we get f=7 ie x=7
