A) \[5\frac{1}{4}days\]
B) \[6\frac{1}{4}days\]
C) \[7\frac{1}{2}\,\,days\]
D) None of these
Correct Answer: B
Solution :
[b] Let As 1 days work = x and Bs 1 days work = y. |
Then, \[x+y=\frac{1}{5}\] |
and \[2x+\frac{1}{3}y=\frac{1}{3}\] |
On solving, we get |
\[x=\frac{4}{25}\] and \[y=\frac{1}{25}\] |
A's 1 day's work \[=\frac{4}{25}\] |
So, A alone could complete the work in \[\frac{25}{4}\,\,or\,\,6\frac{1}{4}\,\,days\] |
