Show answer & explanation
Correct answer: A
Concept
To find a percentage share, multiply the total by the percentage and divide by 100.
For two periods, compute each actual quantity separately; then subtract the smaller quantity from the larger quantity to obtain the absolute difference.
Application
Model-B production in 2019 = 35 × 15/100 = 5.25 lakh.
Model-B production in 2020 = 44 × 20/100 = 8.80 lakh.
Difference = 8.80 − 5.25 = 3.55 lakh.
Cross-check
Adding the difference back to the smaller production gives 5.25 + 3.55 = 8.80 lakh, which reproduces the 2020 Model-B quantity.
Therefore, the required difference is 3.55 lakh.
