A candidate is expected to calculate the missing value, It is required to answer the given question on the basis of the given data and the information. In May, the respective ratio of amount allocated for commission and amount allocated for discount and others was $4 : 3$. What was the Gross revenue of the magazine in May?

### Concept & Formula Use the given ratio to find the missing commission amount, and then calculate the Gross Revenue by summing up all the components. $$ \text{Gross Revenue} = \text{Net Revenue} + \text{Commission} + \text{Discount} $$ ### Step-by-Step Solution 1. **Given for May:** - Discount = ₹ 36000 - Ratio of Commission to Discount = $4 : 3$ 2. **Calculate Commission:** - Let Commission be $4x$ and Discount be $3x$. - $3x = 36000 \implies x = 12000$ - Commission = $4 \times 12000 = 48000$ 3. **Calculate Gross Revenue:** - Gross Revenue = $336000 \text{ (Net)} + 48000 \text{ (Commission)} + 36000 \text{ (Discount)}$ - Gross Revenue = $420000$ ### Exam Strategy & Shortcut Notice that $3 \text{ units} = 36k$, so $1 \text{ unit} = 12k$. The commission is $4 \text{ units} = 48k$. Simply add $336k + 48k + 36k = 420k$. ### Common Pitfall Reversing the ratio (e.g., treating the commission as 3 parts instead of 4) will result in calculating the wrong commission and subsequently the wrong Gross Revenue. ### Final Answer Therefore, the correct answer is **₹ 420000**.
