A number P4571203R is divisible by 18.Which one of the following values can P and R take?

1) 1,2
2) 2,3
3) 6,8
4) 3,3

• Ans:) (p,q) = (6,8).
  P4571203R if it is divisible by 18 den it should be divisible by 2 and 9 ...
  if it is divisible by 2 den last number should be multiple of 2 now two options are eliminated..?
  from remaining two options sum of all numbers in P4571203R should divisible by 9 if you take (p,q) = (1,2) den sum of all digits = 25 it is not divisible by 9 so option 1 is wrong .
  If you take (p,q) = (6,8) den sum of all numbers = 36 it is divisible by 9
  so correct option is (p,q) = (6,8)...
