Draw the graphs for the following tables of values, with suitable scales on the axes. (a) Cost of apples Number of (b) Distance travelled by a car, Time (i) How much distance did the car cover during the period 7.30 a.m. to 8 a.m? (ii) What was the time when the car had covered a distance of `100 km` since it’s start? (c) Interest on deposits for a year. Deposit Simple Interest (i) Does the graph pass through the origin? (ii) Use the graph to find the interest on `Rs 2500` for a year. (iii) To get an interest of `Rs 280` per year, how much money should be deposited?

Explanation

(a) Taking a suitable scale:

For x-axis, 2 unit = 1 apple and
for y-axis, 2 unit = Rs 5.
We can mark the number of
apples on x-axis and the cost of apples on y-axis.

A graph of the given data is as follows.

(b) Taking a suitable scale

For x-axis, 4 units = 1 hour
and for y-axis, 2 units = 20 km,

We can represent the time on x-axis and the distance
covered by the car on y-axis.

A graph of the given data is as follows.
