The following chart shows the distribution (percentage-wise) of the total number of computers sold by dealers A and B together during 5 months. Study the chart and answer the given question. Total number of computers sold by dealers A and B in March = 576 The ratio of computers sold by dealers A and B in February is 6 : 5. The difference between the number of computers sold by A and B is x. The value of x will be between _______.
Calculation:
From the pie chart, 24% or 576 computers were sold by dealers A and B in March.
Total computers sold = \(576\over24\) × 100 = 2400
Computers sold during February = \(18\over100\) × 2400 = 432
Difference of the ratio of the computers sold by A and B = \(1\over11\) × 432 = 39
∴ The difference in the computers sold by A and B is around 39.
