Mark the correct alternative in each of the following:

Let S be the sum, P be the product and R be the sum of the reciprocals of 3 terms of a G.P. then P2R3 : S3 is equal to


Let, 3 terms of the G.P. be a , a, ar


S = a + a + ar =



P = a × a × ar = a3


P2 = a6


R = ra + 1a + 1ar =



Then, P2R3 : S3


⇒


⇒


⇒ 1 : 1
