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

  1. Rs 16

  2. Rs 20

  3. Rs 24

  4. Rs 28
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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
