Show answer & explanation

Correct answer: B

Concept

A percentage expresses a part out of every 100 units. To find a given percentage of a total, multiply the total by the percentage written as a fraction over 100.

If a percentage from one year is applied to another year, the new year’s total is the base; the original year’s absolute count is not carried over.

Application

  1. The hypothetical percentage for Model A in 2020 is the 2019 percentage, 30%.

  2. Use the 2020 total of 44 lakh laptops as the base.

  3. Required production = 30/100 × 44 lakh = 0.30 × 44 lakh = 13.2 lakh.

Cross-check

Since 10% of 44 lakh is 4.4 lakh, three such parts give 30%: 3 × 4.4 lakh = 13.2 lakh.

Result

Therefore, the hypothetical production of Model A in 2020 would have been 13.2 lakh laptops.
