1. Check whether 4335 is divisible by 17 or not?Solution:Divisibility rule of 17 :
5 times the last digit and subtract it from the rest of the number.
If the answer is divisible by 17, then number is also divisible by 17.
(Apply this rule to the answer again if necessary)
`433color{red}{5}=>433 - color{red}{5} xx 5 = 433 -25 = 408`
`40color{red}{8}=>40 - color{red}{8} xx 5 = 40 -40 = 0`
Here 0 is divisible by 17.
