If s is the product of the integers from 70 to 80 inclusive, and if t is the product of the integers from 70 to 81 inclusive, what is 1/s + 1/t in terms of t? Choose the correct option
A) 32/t B) 42/t C) 52/t D) 62/2t E) 82/t
Similarly in the actual problem   s =t/81. 1/s = 1/(t/81) or 1/s = 81/t   1/s + 1/t = 81/t + 1/t = 82/t   82/t
