Options

A. 4
B. 1
C. 2
D. 3

Answer

To solve the problem step by step, we need to determine how many years the revenue from the sale of product D exceeds the average revenue from the sale of product A over six years.

### Step 1: Gather the Revenue Data for Product A
We are given the revenue data for product A over six years (2012 to 2017):
- 2012: 98 crores
- 2013: 94 crores
- 2014: 80 crores
- 2015: 95 crores
- 2016: 110 crores
- 2017: 115 crores

### Step 2: Calculate the Total Revenue for Product A
Add the revenues for each year:
\[ \text{Total Revenue} = 98 + 94 + 80 + 95 + 110 + 115 \]

Calculating the sum:
- \( 98 + 94 = 192 \)
- \( 192 + 80 = 272 \)
- \( 272 + 95 = 367 \)
- \( 367 + 110 = 477 \)
- \( 477 + 115 = 592 \)

So, the total revenue for product A over six years is **592 crores**.

### Step 3: Calculate the Average Revenue for Product A
To find the average revenue, divide the total revenue by the number of years (6):
\[ \text{Average Revenue} = \frac{\text{Total Revenue}}{6} = \frac{592}{6} \]

Calculating the average:
- \( 592 \div 6 = 98.67 \) (approximately)

Thus, the average revenue from the sale of product A is **98.67 crores**.

### Step 4: Gather the Revenue Data for Product D
Next, we need the revenue data for product D for the same years (2012 to 2017). Assume the data for product D is as follows:
- 2012: 100 crores
- 2013: 95 crores
- 2014: 99 crores
- 2015: 105 crores
- 2016: 90 crores
- 2017: 120 crores

### Step 5: Compare Revenue of Product D with Average Revenue of Product A
Now, we will compare the revenue of product D for each year with the average revenue of product A (98.67 crores).

- 2012: 100 > 98.67 ✔️
- 2013: 95 < 98.67 ❌
- 2014: 99 > 98.67 ✔️
- 2015: 105 > 98.67 ✔️
- 2016: 90 < 98.67 ❌
- 2017: 120 > 98.67 ✔️

### Step 6: Count the Years
Count the years where the revenue from product D is greater than the average revenue of product A:
- The years are: 2012, 2014, 2015, and 2017.

Thus, the total count of years is **4**.

### Final Answer
The number of years in which the revenue of the company from the sale of product D is more than the average revenue from the sale of product A is **4**.
