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 laborer per day is

• A. $Rs16$
• B. $Rs20$
• C. $Rs24$
• D. $Rs28$

Answer 1

The correct option is A $Rs16$

The average wage$=\frac{18\times 12+10\times 13.50+5\times 25+42\times 2}{35}$

$\Rightarrow \frac{216+135+125+84}{35}=\frac{560}{35}=Rs.16$
