Total expenditure of companies A and B together in 2014 was Rs. `13.5` lac. What was the total income of the tow companies (in Rs. Lac) in that year ?

Options

A. `19.757`
B. `20.25`
C. `19.75`
D. Cannot be determined

Answer

D

Explanation

Let the expnditure of company 'A' be Rs. A
Then, expnditure of company B=Rs. (13.5-a) lac
Now, `((I_(1)-a))/(a)xx100=45" "` [ company A]
and `([I_(2)-(13.5-a)])/((13.5-a))xx100=50" "` [ company B]...(ii)
Here, we have three unknows but two equations.
Hence, `I_(1)+I_(2)` cannot be determined.
