If s is the product of the integers from 10 to 20 inclusive, and if t is the product of the integers from 10 to 21 inclusive, what is 1/s + 1/t in terms of t?	Choose the correct choice from the following answers
A) 22/t
B) 24/t
C) 26/t
D) 28/t
E) 30/t
Similarly in the actual problem   s =t/21. 1/s = 1/(t/21) or 1/s = 21/t   1/s + 1/t = 21/t + 1/t = 22/t   22/t
