The pie chart given below shows the number of keys manufactured by 5 machines. The data is presented in the terms of degrees.
Average number of keys manufactured by M3 and M5 = 1500.

What are the total number of keys manufactured by the given 5 machines?
Show answer & explanation
Correct answer: D
Explanation
Given:
M3 = 72°, M5 = 78°
Average of M3 and M5 = 1500
M3 + M5 = 1500 × 2 = 3000
Angle = 72 + 78 = 150°
150° = 3000 ⇒ 1° = 20
Total Angle = 360°
Total Number = 360 × 20 = 7200
