A product gets 0 at its end when
(i) a multiple of 5 is multiplied by an even number or
(ii) a multiple of 10 is multiplied by any number. All the given numbers are even and do not contain any multiple of 5. So, zeros at the end of the
product will come only on multiplications by multiples of 10.
Multiples of 10 that lie in the given range from 2 to 100 are 10,
20, 30, 40,50, 60, 70, 80, 90 and100. Each of these multiples will
yield one zero except 100 which will yield two zeros at the end of the product.
Total no. of zeros at the product = 9 + 2 = 11
