s = 100*101*....200
t = 100*101*.....200*201
t = s*201

1/s + 1/t = (t+s)/st

(t/201 + t)/ (t^2/201)
202t/t^2
202/t

s= 100*....*200
t= 100*....*200*201

effectively s=t/201 (since we want the answer in terms of t)

now 1/s + 1/t = 1/(t/201) + 1/t

which is (201/t) + 1/t

base is same and taking out common... 201 and 1 add up
giving 202/t answer is D pretty simple!

S*t=100..*200

t=100*...201

1/s+1/t=s+t/st=(100*...200)+(100*...201)/((100*...200)*(100*...201))

=(100*...200)(1+201)/(((100*...200)*(100*...201)))

=202/(100*...201)=202/t

Pick D
