Answer 1

The Correct Option is C

We need to calculate the percentage increase in sales revenue for Store Q from January to March.
- Step 1: Extract data for Store Q. From the table:
- January: 15 lakhs.
- March: 25 lakhs.
- Step 2: Calculate the absolute increase.
\[ \text{Increase} = 25 - 15 = 10 \] - Step 3: Compute percentage increase.
\[ \text{Percentage increase} = \left( \frac{\text{Increase}}{\text{January revenue}} \right) \times 100 = \left( \frac{10}{15} \right) \times 100 = \frac{100}{1.5} \approx 66.67% \] - Step 4: Verify.
\[ 15 \times \left(1 + \frac{66.67}{100}\right) = 15 \times 1.6667 \approx 25 \] Correct.
- Step 5: Check options.
- (a) 50%: \( \frac{10}{15} \times 100 \neq 50 \).
- (b) 60%: \( \frac{10}{15} \times 100 \neq 60 \).
- (c) 66.67%: Correct.
- (d) 75%: \( \frac{10}{15} \times 100 \neq 75 \).
- Step 6: Alternative metho(d) Ratio: \( \frac{25}{15} = \frac{5}{3} \approx 1.6667 \). Increase = \( (1.6667 - 1) \times 100 \approx 66.67% \).
Thus, the answer is c.

Answer 2

We need to find the store with the highest total sales revenue.
- Step 1: Calculate total revenue for each store.
- Store P: \( 20 + 25 + 30 = 75 \) lakhs.
- Store Q: \( 15 + 20 + 25 = 60 \) lakhs.
- Store R: \( 30 + 35 + 40 = 105 \) lakhs.
- Store S: \( 10 + 15 + 20 = 45 \) lakhs.
- Step 2: Compare totals.
- P: 75, Q: 60, R: 105, S: 45.
- Highest = 105 (Store R).
- Step 3: Verify. Recalculate R: \( 30 + 35 + 40 = 105 \). Correct.
- Step 4: Check options.
- (a) Store P: 75, incorrect.
- (b) Store Q: 60, incorrect.
- (c) Store R: 105, correct.
- (d) Store S: 45, incorrect.
- Step 5: Alternative metho(d) Compare monthly values; R consistently has high revenues.
Thus, the answer is c.

Answer 3

We need to identify the month with the lowest total sales revenue across all stores.
- Step 1: Sum revenues for each month.
- January: \( 20 + 15 + 30 + 10 = 75 \) lakhs.
- February: \( 25 + 20 + 35 + 15 = 95 \) lakhs.
- March: \( 30 + 25 + 40 + 20 = 115 \) lakhs.
- Step 2: Compare totals.
- January: 75, February: 95, March: 115.
- Lowest = 75 (January).
- Step 3: Verify. Recalculate January: \( 20 + 15 + 30 + 10 = 75 \). Correct.
- Step 4: Check options.
- (a) January: 75, correct.
- (b) February: 95, incorrect.
- (c) March: 115, incorrect.
- (d) All equal: Incorrect, totals differ.
- Step 5: Alternative metho(d) Observe trend: Revenues increase each month, so January is lowest.
Thus, the answer is a.

Answer 4

We need the average sales revenue per store in February.
- Step 1: Extract February revenues.
- P: 25, Q: 20, R: 35, S: 15.
- Step 2: Sum revenues.
\[ 25 + 20 + 35 + 15 = 95 \] - Step 3: Calculate average. Number of stores = 4.
\[ \text{Average} = \frac{95}{4} = 23.75 \] - Step 4: Verify. Add: \( 25 + 20 = 45 \), \( 45 + 35 = 80 \), \( 80 + 15 = 95 \). Divide: \( 95 \div 4 = 23.75 \). Correct.
Thus, the answer is 23.75.
