    5 women can clear a piece of land in 4 days. How many more women will be required to clear it in one day?

    A)  \[10\]                                                  

    B)  \[20\]                  

    C)         \[25\]                  

    D)         \[15\]                  

    Correct Answer: D

    Solution :

    Let the number of women needed to clear the land in 1 day be 'x? Number of women and number of days are inversely proportional. \[\therefore \] \[5:x\,\,:\,\,\,:\,\,1:4\] \[\Rightarrow \]               \[x=4\times 5=20\] \[\therefore \]   Number of more women required \[=20-5=15\].
