your number when divided by 4 leaves a remainder of 3
when divided by divided by 5, leaves a remainder of 2
numbers which fit the first case:
7 11 15 19 23 27 31 35 39
numbers which fit the 2nd case:
7 12 17 22 27
the least number would be 7, but I have a feeling they are looking for 27
check:
7 ---> one row of 4, with 3 left over
7 ---> one row of 5, with 2 left over
27 ---> 6 rows of 4, with 3 left over
27 ---> 5 rows of 5, with 2 left over
