The following table shows the percentage distribution of five different Models (A-E) of Mobile Phones produced by a company during the years 2021 and 2022. Total number of Mobile Phones produced by the company in 2021 and 2022 is 4,50,000 and 5,20,000, respectively. Based on the data in the table, answer the questions 1-5
Year-wise Percentage (%) Distribution of Model of Mobile Phones.

If 85% of the number of Model-E Mobile phones produced by the company during 2021 and 2022 were sold, then how many Model-E Mobile phones were left unsold by the company?

Correct option is B

Number of Model-E phones in 2021 = 20% of 4,50,000 = 0.20 * 4,50,000 = 90,000
The number of Model-E mobile phones produced in 2022: Number of Model-E phones in 2022 = 10% of 5,20,000 = 0.10 * 5,20,000 = 52,000
The total number of Model-E phones produced in both years: Total Model-E phones = Number in 2021 + Number in 2022 Total Model-E phones = 90,000 + 52,000 = 142,000
The number of Model-E phones sold (85% of the total): Number of Model-E phones sold = 0.85 * Total Model-E phones = 0.85 * 142,000 = 120,700
The number of Model-E phones left unsold: Number of Model-E phones left unsold = Total Model-E phones - Number of Model-E phones sold Number of Model-E phones left unsold = 142,000 - 120,700 = 21,300
So, the company left 21,300 Model-E mobile phones unsold.
