Ask EduPadi AI for a detailed answer
Correct Option: A
Let the number of days worked by the assistant = d
\(\therefore\) The bricklayer worked (d + 10) days.
1500(d + 10) + 500(d) = N 95,000
1500d + 15,000 + 500d= N 95,000
2000d = N 95,000 - N 15,000
2000t = N 80,000
d = 40 days
\(\therefore\), the assistant worked for 40 days and received N (500 x 40)
= N 20,000
