Answer / Solution

Firstly ,we will calculate the increase in percentage-
1)Raw material=Annual expenditure in 2010 x 100/Annual expenditure in 2011
Raw material=5200 x 100/6240=83.33%

2)Power and fuel=7000 x 100/9450=74.07%

2)Salary and wages=9000 x 100/12600=71.43%

3)Plant and machinery=20000 x 100/25000=80%

4)Advertising=15000 x 100/19500=76.92%

5)Research and development=22000 x 100/26500=83.01%
Here, Option D is correct.
