A) One-fourth of the work
B) One-third of the work
C) Half of the work
D) Whole of the work
Correct Answer: C
Solution :
Since, Ram can do a piece of work in 6 days. \[\therefore \]One day's work of Ram \[=\frac{1}{6}\] Shyam can finish the same work in 12 days. \[\therefore \]One day's work of Shyam\[=\frac{1}{12}\] Hence, one day's work together. Ram and Shyam \[=\frac{1}{6}+\frac{1}{12}=\frac{2+1}{12}=\frac{3}{12}=\frac{1}{4}\] \[\therefore \]Two day's work together\[=\frac{1}{2}\] Thus, if they work together for 2 days, then half of the work will be complete.
