|(A)||Raw material and Salary & wages|
|(B)||Salary & wages and Advertising|
|(C)||Power & fuel and Advertising|
|(D)||Raw material and Research & Development|
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.
