**Answer:**

Option B

**Explanation:**

Profit percent earned by company B in 2009 = 35%

Profit percent earned by company B in 2010 = 50%

Expenditure of company B in 2009 = 12 lakhs

Expenditure of company B in 2010 = 14.5 lakhs

Income of company B in 2009 = 35%

= $\frac{I-E}{E}\times100$

35 = $\frac{I-12lakh}{12 lakh}\times100$

(35 x 12) Lakh = 100I - 1200 lakh

420 lakh = 100I - 1200 lakh

I = 16.20lakh

lncome of company B in 2009 = 50%

= $\frac{I-E}{E}\times100$

50 = $\frac{I-14.5 lakh}{14.5 lakh}\times100$

(50 x 14.5) lakh = 100I - 14.50 lakh

2175 = (100) I = I = 21.75 lakhs

So, total income of company B in 2009 and 2010 = 16.2 + 21.75 = 37.95 Lakhs
