Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 9.9%

Explanation:

According to the given chart,

The total number of computers sold in April and May = (99°+45°)360°×5400{(99° + 45°) \over 360°} \times 5400 = 144°360°×5400{144° \over 360°} \times 5400 = 2160

The number of computers sold in January and March = (77°+54°)360°×5400{(77° + 54°) \over 360°} \times 5400 = 131°360°×5400{131° \over 360°} \times 5400 = 1965

Now the difference = 2160 - 1965 = 195

So, the required percentage = 1951965×100{195 \over 1965} \times 100 = 9.9%

Hence the required answer is 9.9%.
