Question

A contractor employed 18 labourers at Rs 12 per day 10 labourers at Rs 13.50 per day 5 labourers at Rs 25 per day and 2 labourers at Rs 42 per day The average wage of a labourer per day is

• A. Rs 16
• B. Rs 20
• C. Rs 24
• D. Rs 28

Answer 1

The correct option is A Rs 16

Total wages paid by contractor to 18 laborers Rs 12 per day =$18\times 12=216 Rs

And total wages paid by contractor to 10 laborers Rs 13.50 per day =$10\times 13.5=135 Rs

And total wages paid by contractor to 5 laborers Rs 25 per day =$5\times 25=125 Rs

And total wages paid by contractor to 2 laborers Rs 42 per day =$2\times 42=84 Rs

Then total wages paid by contractor to all laborers=216+135+125+84=560 Rs

And total laborers=18+10+5+2=35

Then average wages =$\frac{560}{35}=16$ Rs
