Below are four equations in x. Assume that ` 0 lt r lt 4`. Which of the following has the largest solution for x ?

A

`5(1+r/pi)^(x)=9`

B

`5(1+r/17)^(x)=9`

C

`5(1+2r)^(x)=9`

D

`5(1+1/r)^(x)=9`

Text Solution

Verified by Experts

The correct Answer is:
B
Given ` 0 lt r lt 4`
in the given options
` ("Base')^(x)=9/5`
for largest value of x, base should be minimum.
`:. " in option B base "(1+r/17)" is minimum for "0 lt r lt 4`.
