Question

Given a number, N = 555 + 175 – 725, then which of the following is true?
N is divisible by both 7 and 13
N is divisible by both 3 and 17
N is divisible by 17 but not 3
N is divisible by 11 but not 17

Answer 1

N = 555 + 175 - 725

= 730 -725

= 5

So N = 5

So it can't be divisible by any of them......
