The salaries of A, B and C are in the ratio $1:3:4$. If these salaries be increased by $5\%, 10\%$ and $15\%$ respectively, then the increased salaries will be in the ratio:

A boy has a few coins of $50, 25$ and $10$ paise in the ratio $1:2:3$ respectively. If the total amount of the coins is $₹6.50$, then, the number of $10$ paise coins is:

$₹2010$ are to be divided among A, B and C in such a way that, if A gets $₹5$, then B gets $₹12$, and if B gets $₹4$, then C must get $₹5.50$. The share of C will exceed that of B by:
