Options

A. `130.5`
B. `96(2)/(3)`
C. `121.5`
D. `99(1)/(3)`

Answer

B

Explanation

Let the expenditure of company B in 2011 be Rs. 100.
Then `((I_(1)-100))/(100)xx100=35`
`rArr I_(1)=100+35=Rs. 135`
Now, expndirture in 2012 =Rs. 9
Now, `((I_(2)-90))/(90)xx100=45`
`rArr 405-101_(2)xx100=45`
`rArr I_(2)=(1305)/(10)=Rs. 130.5`
Hence, requirex `% =(130.5xx100)/(135)=96(2)/(3)%`
