(7/8)c. If R is the set of all integers from a to c, inclusive, what fraction of c is the median of set
R?

Hi Parallel,

I was unable to solve your problem because one of the numbers was mistyped and displayed a smiley face instead! Could you please retype your question? Thanks!

With 7/8, I got 1/2 as the answer. Can you please tell how you got 11/16? I solved it using numbers. So it wasn't the fastest way.

Can someone solve the problem? I wanted to see if my apprach is different and if there is an easier way to solve then by choosing numbers.

S [a-b] = 3/4 b

(a+b)/2 = 3/4 b
2a = b

Q [b-c] = 7/8 c

(b+c)/2 = 7/8 c

b=3/4 c

Therefore,

a=3/8 c
b= 3/4 c

R [a-c] = ?

(a+c)/2 = [(3/8)c +c]/2 = (11/16) c

Hence C is the answer.

let me know if you have any questions.

Thanks for your explanation. I assume you based it on the theory that Average of consecutive integers is equal to Median ? Not sure how I missed it, damn!
