what is the smallest no . which must be added to 27452 so as to obtain a sum which is divisible by 9 ?
"for 27452 , 2 + 7 + 4 + 5 + 2 = 20 . 7 must be added to 27452 to make it divisible by 9 . now , 2 + 7 + 4 + 5 + 9 = 27 = > 27 is a multiple of 9 and hence 27452 is also divisible by 9 a"
divide(multiply(27452, 9), 27452)
