Data related to number of bags sold by two stores (M and N) during 5 years :

Question 50

If the average number of bags sold by store M in 2011, 2012 and 2013 was 350, what was the number of bags sold by the same store in 2013?

Solution

Average no. of bags sold by store M in the three years = 350

Total no. of bags sold in 2011, 2012 & 2013 = 350*3 = 1050

Bags sold by store M in 2011 = 250

Bags sold by store M in 2012 = 260

Bags sold by store M in 2013 = 1050 - (250 + 260) = 1050 - 510

= 540
