A bricklayer charges ₦1,500 per day for himself and ₦500 per day for his assistant. If a two bedroom flat was built for ₦95,000 and the bricklayer worked 10 days more than his assistant, how much did the assistant receive?
A.
N20,000
B.
N28,000
C.
N31,200
D.
N41,000
Correct Answer: N20,000
Explanation
Let the number of days worked by the assistant = t
∴
The bricklayer worked (t + 10) days.
1500(t + 10) + 500(t) = N 95,000
1500t + 15,000 + 500t = N 95,000
2000t = N 95,000 - N 15,000
2000t = N 80,000
t = 40 days
∴
The assistant worked for 40 days and received N (500 x 40)
= N 20,000
Let the number of days worked by the assistant = t
∴
The bricklayer worked (t + 10) days.
1500(t + 10) + 500(t) = N 95,000
1500t + 15,000 + 500t = N 95,000
2000t = N 95,000 - N 15,000
2000t = N 80,000
t = 40 days
∴
The assistant worked for 40 days and received N (500 x 40)
= N 20,000
