If the time of borrowing when the Principal $=₹600$, $S.I.=₹12.6$, Rate $=3.5\%$ per annum is $k$ years, then find $k$.

A certain amount of money amounts to $₹4400$ in two years and to $₹4600$ in three years. Find the Principal and the Rate of interest.

$₹4000$ borrowed amounts to $₹5400$ in $5$ years. How much will $₹5600$ amount to in three years at the same rate as above?

Find the interest on a deposit of $₹3650$ from January $3, 2002$ at the Rate of $10\%$ per annum up to March $17, 2002$.

Find the amount directly using the formula $A=P\left(1+\frac{R\times T}{100}\right)$ if Principal$=₹5000$, Rate $=10\%$ per annum and Time $=3$ years.

Find the amount directly using the formula $A=P\left(1+\frac{R\times T}{100}\right)$ if Principal $=P=₹450$, Rate $=7\%$ and Time $=5$ years.

Find the amount directly using the formula  $A=P\left(1+\frac{R\times T}{100}\right)$ if Principal $=₹3200$, Rate $=7.5\%$, Time $=2\frac{1}{2}$ years.

If the amount is $₹k$ by directly using the formula $A=P\left(1+\frac{R\times T}{100}\right)$ if Principal $=₹720$, Rate $=8.5\%$ per annum and Time $=3$ years, then find the value of $k$
