Question : The following pie chart shows the number of emails (in hundreds) received by 8 different persons, P1 to P8.
P5 and P8 together have received what percentage of the total emails received by these 8 persons taken together?
Option 1: 19%
Option 2: 21%
Option 3: 16%
Option 4: 17%
Correct Answer: 17%
Solution :
Total emails = P1 + P2 + P3 + P4 + P5 + P6 + P7 + P8
= 43 + 57 + 61 + 39 + 24 + 56 + 76 + 44 = 400
⇒ Emails by received by P5 and P8 = P5 + P8 = 22 + 44 = 68
The required percentage $=\frac{\text{Value}}{\text{Total value}}× 100 = \frac{68}{400} × 100 = 17$%
Hence, the correct answer is 17%.
