Accepted Answer

Step 1: Extract the production data for B and D from 2018 to 2023.
Brand B: 23, 37, 28, 32, 34, 26
Brand D: 35, 37, 42, 32, 36, 28

Step 2: Calculate the average production for each brand over the 6 years.
Average for B = (23 + 37 + 28 + 32 + 34 + 26) / 6 = 180 / 6 = 30 lakhs
Average for D = (35 + 37 + 42 + 32 + 36 + 28) / 6 = 210 / 6 = 35 lakhs

Step 3: Find the difference between the averages.
Difference = 35 - 30 = 5 lakhs

Therefore, the difference in the average production of B and D during 2018-2023 is 5 lakhs.
