The given pie chart represents the percentage of people in a city who are interested to buy the laptop of five different companies - A, B, C, D and E.
The number of people interested to buy company A's laptop is what percentage of the number of people interested to buy company D's laptop?
Answer & explanation
Correct answer: option 4
Number of company A's laptop = \(\frac{31}{100}\) × 52000
= 16120
Number of company D's laptop = \(\frac{20}{100}\) × 52000
= \(\frac{1}{5}\) × 52000
= 10400
Required percentage = \(\frac{16120}{10400}\) × 100
= 155%
