Question 56

The Table given below presents the annual expenses(in thousands) on various heads made by a firm during 2006-2010.

By how much percentage (correct up to two decimal places) is the average expenditure on purchases more than the average expenditure on rent?

Solution

Average expenditure on purchases = $$\frac{23500+28500+38500+41000+50000}{5}$$

= $$\frac{181500}{5}$$

= 36300

Average expenditure on rent = $$\frac{40000+34000+36000+20000+28000}{5}$$

= $$\frac{158000}{5}$$

= 31600

Percentage more = $$\frac{\left(36300-31600\right)}{31600}\times100$$

= $$\frac{4700}{31600}\times100$$

= 14.87%
