Five two-digit numbers are multiples of the products of their digits. Four of these numbers are 11, 12, 24, and 36. Find the fifth number.
I was looking at this and confuse about this question.
Thank you for helping me,
Ok, we have
11: 1x1=1, 11 is a multiple of 1
12: 1x2=2, 12 is a multiple of 2
24: 2x4=8, 24 is a multiple of 8
36: 3x6=18, 36 is a multiple of 18
Does this make sense?
If so you can now find your 5th number, there's not that many to choose from i.e. between 10 & 99
