15（0） 3（0)0 24（0） 8（2）（5）

A number minus 8 is a multiple of 2, 5 and 3. What is the maximum number?

This only has the minimum value, 38, no maximum, as long as it is a multiple of 30 plus 8, you can meet this condition

Some cards are written in multiples of 3 or 4. There are 15 cards in which multiples of 3 account for 2 / 3, multiples of 4 account for 3 / 4 and multiples of 12?
I want the process

2 / 3 + 3 / 4-1 = 5 / 12
Total 15 / (5 / 12) = 36
