A) 24 days
B) 32 days
C) 40 days
D) 48 days
Correct Answer: D
Solution :
Time taken by A + B + C \[=\frac{12\times 8\times 6}{12\times 8+8\times 6+6\times 12}\times 12\] \[=\frac{1152}{216}\] Work done by B in 1 day \[=\frac{216}{1152}-\frac{1}{6}=\frac{216-192}{1152}\] \[=\frac{24}{1152}=\frac{1}{48}\text{part}\]You need to login to perform this action.
