Question

Test the divisibility of 93324 by 2, 3, 4, and 5 *

Answer 1

Answer:

If the difference of the sum of its digits at odd places and sum of its digits at even places is either 0 or multiple of 11 then the given number is divisible by 11

83721

Sum of the digits at odd places =1+7+8=16

Sum of the digits at even places =2+3=5

Difference of the two sums =16−5=11

∴83721 is divisible by 11
