Given the reminder of a number when it is divided by a certain divisor.Finding the reminder if the same number is divided by another divisor

A number when divided by 32 gives a the reminder 29.This number when divided by 8 will leave the reminder
a] 3 b] 5 c] 7 d] 29                                                                                                                     Ans 5

let the number be x,
When it is divided by 32,let the quotient be k and reminder 29
32) x (k
      ---
      29

therefore x = 32k  + 29
                  = [(8 * 4 * k) + (8*6) - 5]
5 is the reminder
