1. Rs56.26 lacs
2. Rs52.46 lacs
3. Rs48.12 lacs
4. Rs46.67 lacs

Solution: Let the expenditure of the company B in the year 2012 = Rs. X lacs

then, $$\frac{5}{X} \times 100 = 12$$ $$X = \frac{5 \times 100}{12}$$ $$X = 41.67 \ lacs$$ Hence, the income of the company B in the year 2012, $$= (5 + 41.67) \ lacs$$ $$= Rs46.67 \ lacs$$
