Arithmetic Mean (Average) of 100 units of currency = Sum of 100 units / 100 = [color=red]50[/color]*100 / 100 = 50
? What is the OA ?

You have the same approach as mine butamitabhprasad wrote:I am getting "C"
50+I/40
Av of 100+1%of I = 50+I/200
Add 2% of I to it = 2*I/100+I/200+50
= I/40+50
Whats OA ?

A = S/n
So, Average of 100 items in the set = Sum of 100 terms / 100
Sum of consecutive numbers can be found by multiplying the number in the middle of the sequence (50) with the number of terms in the sequence
==> 50 * 100 ==> 5000
Average = 5000 / 100 = 50
This is how I got 50.
