A) 12 days
B) 4 days
C) 8 days
D) 16 days
Correct Answer: C
Solution :
\[\because \] Prabhat does \[\frac{1}{2}\]work in 12 days. \[\therefore \]Prabhat will do 1 work in \[12\times 2=24\]days. Similarly, Santosh will do 1 work in 12 days. \[\therefore \] One day?s work of Santosh and Prabhat \[=\frac{1}{24}+\frac{1}{12}=\frac{1+2}{24}=\frac{3}{24}=\frac{1}{8}\] \[\therefore \]Required time = 8 days
