If the number of 741,61n, where n represents the ones digit, is a multiple of 3, then the value of n could be which of the following?
Choose the correct answer:
A) 7	B) 6	C) 5	D) 4	E) 3
Then for any number to be a multiple of 3,The sum of its digits should be the multiple of 3.   i.e 7+4+1+6+1+n= multiple of 3   or, 19 + n = multiple of 3.   If n=5, 19 + n =24,which is a multiple of 3.   Hence answer is 5.
