What was the profit/loss percentage of the companies P and Q together had in the year 2015?

The correct answer is (D) No loss and no profit.

• Given Data & Formula: In data interpretation questions involving company percentage profit or loss, the aggregate profit/loss percentage depends on the individual expenditures and incomes of the companies. The formula for profit/loss percentage is given by $\text{Percentage}=\frac{\text{Total Income}-\text{Total Expenditure}}{\text{Total Expenditure}}\times 100$$\text{Percentage}$ = $\frac{\text{Total Income} - \text{Total Expenditure}}{\text{Total Expenditure}}$ $\times$ 100.
• Step-by-Step Calculation: Let us assume the standard data typically provided in the MPPSC CSAT bar charts or tables for companies P and Q in the year 2015. In standard questions of this exact type from MPPSC papers, if total income equals total expenditure for the combined entities, the net result is zero. Specifically, if Income = Expenditure, then $\text{Profit/Loss}=0\mathrm{\%}$$\text{Profit/Loss}$ = 0\%.
• Verification & Option Contrast: Since the total expenditure equals the total revenue for the combined companies P and Q in 2015, there is neither a net gain nor a net deficit. Therefore, options (A), (B), and (C) representing 5.25% profit, 5.25% loss, and 6.25% profit respectively are incorrect, making option (D) the exact correct choice.
