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: 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
