Question

A bank gives 10% interest on the deposited by the ladies. Draw a graph showing the relation between the amount deposited and the simple interest earned by the ladies. Find the annual interest earned for an investment of ₹250.

$\begin{array}{ccccc}\text{Sum Deposited(in ₹)}100& 200& 300& 500& 1000\\ \text{Simple interest(in ₹)}10& 20& 30& 50& 100\end{array}$

• A. ₹25
• B. ₹35
• C. ₹50
• D. ₹75

Answer 1

The correct option is A ₹25

Among the given data the simple interest obtained is dependent on the sum deposited. So, 'Simple Interset' will be the dependent variable and 'Sum Deposited' is independent variable.

On graph dependent variables are represented on Y-axis and indepoedent variable on X-axis. So the given table can be represented as: (100,10), (200, 20), (300, 30), (500, 50), (1000, 100).

Now, on plotting the points obtained graph is :

From the graph, we observe that:

₹25 is earned as an annual interest for an investment of ₹250.
