In 2001, the approximate percentage of profit/loss of all the five companies taken together is equal to-

Answer: Option C

  Total income of all the five companies
  = Rs. (35 + 50 + 40 + 40 + 50) crores
  = Rs. 215 crores
  Total expenditure of all the five companies
  = Rs. (45 + 40 + 45 + 30 + 45) crores
  = Rs. 205 crores
$$\begin{array}{rl}& \therefore \text{ Profit percent}\\ & =\frac{\text{Income - Expenditure}}{\text{Expenditure}}\times 100\\ & =\frac{215-205}{205}\times 100\\ & =\frac{1000}{205}\\ & =4.88\%\end{array}$$
