Question

Amounts donated by eight students to ‘NIVAR’ cyclone effected people are ₹300, ₹450, ₹700, ₹650, ₹400, ₹750, ₹900 and ₹850. Find the Arithmetic Mean of amounts donated.

Answer 1

Given data, ₹300, ₹450, ₹700, ₹650, ₹400, ₹750, ₹900 and ₹850. 

Sum of observations = 300 + 450 + 700 +650 +400 + 750 + 900 + 850 = 5000 

Number of observations = 8 

∴ Arithmetic Mean = \(\frac {Sum\,of\, observations}{Number\,of\,observations}\) = 5000/8 = ₹625

∴ Arithmetic Mean of amount donated = ₹625
