Introduction to Simple Interest

A man deposits a part of his savings in a bank and the remaining part in the post office on simple interest. The rate of simple interest of the bank and post office are $10\%$ and $8\%$ respectively and the total amount of his savings is $₹57000$. If he deposits the total savings in the bank, he would get $₹500$ more as interest. What amount of money was deposited in the bank and the post office?

What is simple interest ?

A certain sum of money amounts to $\mathrm{Rs}. 10080$ in $5$ years at $8\%$. The principal amount is:

Ramesh deposits $₹2,400$ per month in a recurring deposit scheme of a bank for one year. If he gets $₹1,248$ as interest at the time of maturity, find the rate of interest and the maturity value of this deposit.

A loan of $₹1200$ was settled after $2 \mathrm{years}$ by paying $₹1320$. If it is settled after $5 \mathrm{years}$, $₹$_____ should be paid.

Lakshmi borrowed $₹6000$ at $5\frac{1}{2}\% \mathrm{p}.\mathrm{a}$. After $2 \mathrm{years}$ she returned $₹3000.$ Again after $2$ more years she settled the loan. If her last payment is $₹k,$ then find the value of $k$.

A certain sum of money would amount to $₹1344$ in $3$ years at $4\%$ p.a is $₹k,$ then find the value of $k$.

The amount of $₹2000$ for  $2\frac{1}{2}\mathrm{years}$ interest at $4 \% \mathrm{p}.\mathrm{a}$ is $₹k$, then find the value of $k$.

Amount for $5$ years $-$ Amount for $3$ years $=$ Interest for how many years?

Sameer lent equal sums of money at $5\frac{1}{2}$ percent and $4$ percent per annum respectively for a period of $3$ years. If he earned $₹72$ more for the money lent out at $5\frac{1}{2}\%$, if the sum of money is $₹k$, then, find the value of $k$ lent at $4\%.$

Sheela has paid simple interest on a certain sum for $4$ years at $9.5\%$ per annum as $₹21280$. If the sum is $₹k$, then find the value of $k$.

 At a rate of $10$p.c.p.a, if the interest on $₹6000$ is $₹600$ for _____ months.

Find the Simple Interest of $₹1500$ at the rate of $4.5\%$ per annum for $4$ years.

Find the Simple Interest of $₹2000$ at the rate of $12\%$ per annum for $3$ years.

Find the Simple Interest of $₹5000$ at the rate of $4\%$ per annum for $5$ years.

Find the Simple Interest of $₹2500$ at the rate of $10\%$ per annum for $2$ years.

Find the Simple Interest of $₹800$ at the rate of $6\%$ per annum for $3$ years.

Find the rate of interest if amount is $₹5000$, simple interest $=₹ 500$, time$=2$ years.

If a bank gives $2.5\%$ interest every year on a term deposit plan, how much interest does a person get when he deposits ₹$2000$ every year for $10$ years.

Calculate the simple interest paid on ₹$15000$ borrowed for $2$ years at $1.5\%$ of interest every year.
