Question

The number of cars sold over a period of six months is shown below in the form of a pictograph.

Complete the above Pictograph and find the ratio of the number of cars sold in April to cars sold in June?

Answer 1

Step 1: Completing the pictograph

As given in the above pictograph, one figure of car represents $10$ cars.

In the second row, Feb month has two and a half pictures of cars, So its value will become $2.5\times 10=25\mathrm{cars}$.

In the third row, March month has five pictures of cars, So its value will become $5\times 10=50\mathrm{cars}$.

In the fifth row, May month has three and a half pictures of cars, So its value will become $3.5\times 10=35\mathrm{cars}$.

In the sixth row, June month has a value equal to $40$, So the number of figures of the car will be $40÷10=4.$

So the required complete pictograph will be as shown below.

Step 2: Finding the required ratio.

From the above pictograph, we have

No. of cars sold in April $=20\mathrm{cars}$

No. of cars sold in June $=40\mathrm{cars}$

Required ratio $=\underset{\mathrm{Number}\mathrm{of}\mathrm{cars}\mathrm{sold}\mathrm{in}\mathrm{June}}{\overset{\mathrm{Number}\mathrm{of}\mathrm{cars}\mathrm{sold}\mathrm{in}\mathrm{April}}{\leftarrow }}$

$\raisebox{1ex}{$=20$}\!\left/ \!\raisebox{-1ex}{$40$}\right.=1:2$

So, the required ratio is $1:2.$
