How many trailing zeros will be there after the rightmost non-zero digit in the value of 25! (factorial 25)?  Choose the correct choice from the following:
A) 25	B) 8	C) 6	D) 5	E) 2
Explanatory Answer   25! means factorial 25 whose value = 25 * 24 * 23 * 22 *....* 1   When a number that has 5 as its factor is multiplied by an even number, it results in a trailing zero.   (Product of 5 and 2 is 10 and any number when multiplied with 10 or a power of 10 will have one or as many zeroes as the power of 10 with which it has been multiplied)   In 25!, the following numbers have 5 as their factor: 5, 10, 15, 20, and 25.   25 is the square of 5 and hence it has two 5s in it.   In toto, it is equivalent of having six 5s.   There are at least 6 even numbers in 25!   Hence, the number 25! will have 6 trailing zeroes in it.   6hoice 6
