The pie chart shows the income of a civil servant in month. If his monthly income is N6,000. Find his monthly basic salary.
A
N2,050
B
N2600
C
N3,100
D
N3,450
correct option: a
The total angle in a pie chart = 360\(^o\).
Hence,
360\(^o\) - (60\(^o\) + 60\(^o\) + 67 + 50 = 237\(^o\))
360\(^o\) - 237 = 130\(^o\)
Salary = \(\frac{123}{360} X \frac{N6000}{1}\)
= N2,050
