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 is A

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
