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
