A man donates 10 of his monthly net earnings to... - JAMB Mathematics 2014 Question
A man donates 10% of his monthly net earnings to his church. If it amounts to N4,500, what is his net monthly income?
A
N40,500
B
N45,000
C
N52,500
D
N62,000
correct option: b
Let;
M = Man monthly net earnings
Then;
\(\text{N4500} = \frac{\text{10%}}{\text{100%}} \times M \)
\(M = \frac{\text{N4500} \times \text{100%}}{\text{10%}} \)
M = N45,000
M = Man monthly net earnings
Then;
\(\text{N4500} = \frac{\text{10%}}{\text{100%}} \times M \)
\(M = \frac{\text{N4500} \times \text{100%}}{\text{10%}} \)
M = N45,000
