If the 26 english alphabets are taken such that a=1 b=2 c=3 =26 then find : (i)the mean and median of the numbers corresponding to the vowels.

A, E, I, O, U are the vowels.
A=1
E=5
I=9
O=15
U=21
To find the mean add all the numbers then divide by how many numbers there are.
1+5+9+15+21=41
41÷5=8.2
(Mean = 8.2)

To find the median put the numbers in numerical order.
1, 5, 9, 15, 21
Then the number in the middle is your number.
(Median = 9)

*Lucky for you it's an odd number so there is a middle.

The answer is c. 7 (i think) i’m almost sure though
