Question

The sum of 5 numbers in a geometric progression is 24. The sum of their reciprocals is 6. The product of the terms of the geometric progression is

(A)36 (B)32 (C)24 (D)18

This question was asked in NSEJS 2018. I need a full solution, please.

Answer 1

Answer:

32 is right answer check it

Answer 2

step by step explanation:

A(r to the power5-1)/(r-1)= sum of 5 terms of gp1=24

1/A(r to the power5-1)/(r-1)=sum of 5 terms of gp2=6

dividing both the eqations u will get

A square=24/6

A=2

We need product of 5terms so taking first term as 2 and the succesive terms as 2^r..2^r^2,,,,,,

therefore, answer is 32.......
