The pie chart given below presents the percentages of the number of motor cycles of diffrent colours out of the total number of motor cycles, parked in an area. The central angles shown in the pie chart are not as per any chosen scale.

Calculation |
|
White colour motor cycles = 18%
|
So, Number of red colour motor cycles = 414 |
⇒ 2300 × 18/100 ⇒ 23 × 18 ⇒ 414 |
|
Blue colour motor cycles = 21%
|
So, Number of red colour motor cycles = 483 |
⇒ 2300 × 21/100 ⇒ 23 × 21 ⇒ 483 |
|
|
Hence, Difference = 69 |
⇒ 483 – 414 = 69 |
