A) 64 days
B) 32 days
C) 16 days
D) 8 days
Correct Answer: B
Solution :
Time taken by Pradeep in doing \[\frac{1}{4}\]work =14 days \[\therefore \]Time taken by Pradeep in doing 1 work \[=14\times 4=56\]days Time taken by Saquib in doing \[\frac{3}{4}\]work = 56 days \[\therefore \]Time taken by Saquib in doing 1 work \[=\frac{56\times 4}{3}\]days \[=\frac{224}{3}\] \[\therefore \](Pradeep + Saquib)'s 1 day's work \[=\frac{1}{56}+\frac{3}{224}\] \[=\frac{4+3}{224}=\frac{7}{224}\] \[\therefore \]Required time \[=\frac{224}{7}=32\]days
