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: Option A
Explanation
Let the number of days worked by the assistant = t
(therefore) 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
(therefore) The assistant worked for 40 days and received N (500 x 40)
= N 20,000
