The following pie chart shows the monthly sales of laptops by five companies (A, B, C, D, and E) in a store.
If 2,500 laptops were sold by the store in a month, then what is the difference between the number of laptops sold by Company A and that of Company C?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 800.
Given that
If 2,500 laptops were sold by the store in a month
The laptops were sold by store A in the month = 40% × 2500
= (40/100) × 2500 = 1000
The laptops were sold by store C in the month = 8% × 2500 = 8 × 2500/100= 200
Hence, the difference between the number of laptops sold by Company A and that of Company C = 1000 - 200 = 800
