A man buys shares at a discount of Rs.x.   Later he sells all but 10 of the shares he purchased at a premium of Rs.x.   If  his  investment  was  Rs.4500  and  proceeds  from  the  sale  were  Rs.6250,  how many shares did he buy originally ?  [Assume face value of shares as Rs.100.]

Rs 4830 is divided among Abhishek, Dishant and Prashant such that if Abhishek's share diminishes by Rs 5, Dishant's share diminishes by Rs 10 and Prashant's share diminishes by Rs 15, their shares will be in the ratio 5:4:3. Find the Dishant's original share?

A sum of money is to be distributed among A, B, C, D in the proportion of 5:2:4:3. If C gets Rs. 1000 more than D, what is B's share?
