\(\frac{\frac{a}{b} + 1}{\frac{c}{b}}\)

In the expression above, a, b and c are different numbers and each is one of the numbers 2, 3 or 5. What is the greatest possible value of the expression?


A. 8/3

B. 4

C. 9/2

D. 5

E. 6


Simplifying,
\(\frac{\frac{a}{b} + 1}{\frac{c}{b}}\)
= \((\frac{a+b}{b})*\frac{b}{c}\)
=\(\frac{a+b}{c}\)

Now, we have to find out the maximum value of \(\frac{a+b}{c}\)
So, (a+b) has to be maximum, i.e 5+3=8 & 'c' has to be minimum i.e, c=2

Hence Max(\(\frac{a+b}{c}\))=\(\frac{8}{2}\)=4

Ans. (B)
