Alex has 4 pens worth of {22, 25, 30, 40}, what is the total mean and median of the worth of pens ?  Choose the correct choice from the following options:
A) 3.42 B) 6.16 C) 8.32 D) 2.0 E) 1.75

Rationale: this is a good question to understand the difference between mean and median . mean : average of all the numbers . ( sum of all the elements divided by the number of elements ) median : arrange the elements of the set in increasing order . if the number of terms is odd , the middle term is the median . if the number of terms is even , the average of middle two terms is the median coming to this question , mean = ( 22 + 25 + 30 + 40 ) / 4 = 29.25 median = ( 25 + 30 ) / 2 = 27.5 total = 1.75 option e
Answer: E
