    X can do a work in 16 days. In how many days will the work be completed by Y if the efficiency of Y is 60% more than that of X?

    A) 10 days                        

    B) 12 days

    C) 25 days                        

    D) 30 days

    Correct Answer: A

    Solution :

    Ratio of time taken by X and Y = 160:100= 1.6:1 Suppose Y takes y days to do the work. Then, 1.6: 1: 16: y \[\Rightarrow \,\,\,\,\,y=\frac{16\times 1}{1.6}\]= 10 days
