Correct Answer: Rs. 5040
Solution :
Given:
Sonu and Monu can do a piece of work in 8 days and 12 days, respectively.
Ratio of their efficiency = $\frac{1}{8}:\frac{1}{12}$ = 3 : 2
Their wages will also be in the same ratio.
$\therefore$ Share of Sonu = $\frac{3}{2+3}\times8400=\frac35\times8400$ = Rs. 5040
Hence, the correct answer is Rs. 5040.
