Find a 2 digit number less than 50 using these clues. It can be divided by 4 exactly. When 4 is added to it, it can be divided by 5 exactly?
It’s divisible by 4, but when 4 is added to it, it’s divisible by 5 means that the number is a multiple

of 4 that when 4 is added to it, it becomes a multiple of 5. Therefore, the number will be 4 less than

a MULTIPLE of 4 & 5. Multiples of 4 & 5 that are less than 50 are: 20 and 40.



Number that's 4 less than 20: 

Number that's 4 less than 40:
