Comprehension:
The COVID lockdown period saw a rise in the sales of bicycles. In the month of September 2020, the sale was twice that of November 2020. The sale of bicycles in September and December 2020 was the same. The sale of bicycles in October 2020 was double that of December 2020. The number of bicycles sold in November 2020 was 2197.

Question 157

# What is the percentage of bicycles sold in November 2020?

Solution

Let's take the number of bicycles sold in November to be x
September had twice the number of bicycles sold, so 2x bicycles were sold in September.
December and September had the same number of bicycles sold, so December also sold 2x bicycles.
October sold double that of December, so there were 4x bicycles sold in October.

The final data is:
September:2x
October: 4x
November: x
December: 2x

The total number of bicycles sold was 9x
The percentage of bicycles sold in November would then be $$\frac{1x}{9x}\times\ 100=11.11\%$$

Therefore, Option C is the correct answer.
