Question : The pie chart given below shows the number of pens sold by each of 8 different shops in a month as a percentage of the total number of pens sold by these 8 shops taken together in that month.
What will be the sum of the central angles made by the sectors A1 and A4?
Option 1: 75.6°
Option 2: 59.6°
Option 3: 84.4°
Option 4: 68.2°
Correct Answer: 75.6°
Solution :
Given:
A1 = 15%
A4 = 6%
We know that,
In a pie chart, 100% = 360°
⇒ 1% = 3.6°
Now, A1 + A4 = 15% + 6% = 21%
So, 21% = 21 × 3.6° = 75.6°
Hence, the correct answer is 75.6°.
