The median will be c as per the given condition, so we have to find if A>c?

(1) e + c = 34
e-c=4
Two equations so we can find e and c, but nothing about a and b

(2) c = a + 10
Now e-c=4
For taking the max value of mean, let us take all unknown values b and d as maximum possible. => b=c and d=e
So mean = \(\frac{a+b+c+d+e}{5}=\frac{c-10+c+c+c+4+c+4}{5}=c-\frac{2}{5}\)<c.
Thus even the maximum possible value of mean, A, is less than c, that is M.
So A<M always
Sufficient

B
_________________

a, b, c, d, and e are five numbers such that a ≤ b ≤ c ≤ d ≤ e and e - c = 4. A is the average (arithmetic mean) of the five numbers, and M is their median. Is A > M?

We need to check, average (arithmetic mean) > median (M), if a, b, c, d, and e are equidistant or not.

Stat1: e + c = 34
So, e= 19 and c= 15, but no idea about a and b, they can be equidistant or not. Not sufficient

Stat2: c = a + 10 or, c-a =10, given, e - c = 4. So we can saw, a, b, c, d, and e are not equidistant. So, definitely, A <M. Sufficient.

So, I think B.

Hi TarunKumar1234,

A small correction here (calculation mistake),
From Statement 1, e = 19 and c = 15.

Hi Bunuel,

A quick query on this question?
a, b, c, d, and e are five numbers....

Here, number means a whole number or a natural number or an integer or a decimal number or any of these?
Although I can see that this number thing doesn't matter in the final answer and doesn't affect our answer choice, I just want to understand for clarity.
TIA.

Regards,
Ravish.

Thanks! It is corrected.

It means real numbers, so it can be integer, fraction, or an irrational number.
