Show answer & explanation
Correct answer: C
Concept
When several categories are requested from a percentage-distribution table, first add their percentages for the specified year.
The required quantity is (combined percentage ÷ 100) × the total quantity for that year.
Application
For 2019, model A accounts for 30%, model B for 15%, and model E for 15%.
Their combined share is 30% + 15% + 15% = 60%.
The total production in 2019 is 35 lakh laptops.
Required production = (60 ÷ 100) × 35 lakh = 21 lakh laptops.
Cross-check
Separately, A, B, and E contribute 10.5 lakh, 5.25 lakh, and 5.25 lakh; their sum is 21 lakh.
Therefore, the total production of models A, B, and E in 2019 was 21.00 lakh laptops.
