Question

107) Choose the number that is different in the set of numbers
A) 110
B) 154
C) 176
D) 180​

Answer 1

There is only one number between 61 and 107 that is a multiple of 3, 5 and 9.

That number is 90.

An easy way to figure this out would be to start with the 9 table…starting in the 60’s.

If it is divisible by, it will also be a multiple of 3. So we really just need a number that is a multiple of both 9 and 5.

…63 72 81 90 ahhh 90 is divisible by 3, 5 and 9 :)
