The monthly salary of a man increased from N2,700 to N3,200. Find the percentage increase
A
10%
B
15%
C
15.6%
D
18.5%
correct option: d
\(\% increase = \frac{Increase}{initial\hspace{1mm} salary}\times 100\%\
Increase=N3,200 - N2,700 = N500\
Initial \hspace{1mm} salary=N2,700.00=\frac{N500}{N2,700}\times 100\% = 18.5\%\)
Increase=N3,200 - N2,700 = N500\
Initial \hspace{1mm} salary=N2,700.00=\frac{N500}{N2,700}\times 100\% = 18.5\%\)
