The following table gives a data from a newspaper survey in Kumasi. 400 people were asked to choose anyone of the newspaper they prefer to read. 5. The pie chart below shows how Mr. Brown spent his salary in the month of January, 2010. He spent Gh¢180.00 on rent.

The total number of people surveyed is 400. The sum of the people who prefer Graphic, Ghanaian Times, Mirror, and Free Press is:

The total number of people is the sum of all categories.

The value of $x$ is $\boxed{\text{50 people}}$.

ii) Draw a pie chart for the distribution.

To draw a pie chart, we first need to calculate the angle for each newspaper category. The total angle in a circle is $360^\circ$.

• Graphic: $\frac{150}{400} \times 360^\circ = 0.375 \times 360^\circ = 135^\circ$
• Ghanaian Times: $\frac{100}{400} \times 360^\circ = 0.25 \times 360^\circ = 90^\circ$
• Mirror: $\frac{75}{400} \times 360^\circ = 0.1875 \times 360^\circ = 67.5^\circ$
• Daily Guide ($x=50$): $\frac{50}{400} \times 360^\circ = 0.125 \times 360^\circ = 45^\circ$
• Free Press: $\frac{25}{400} \times 360^\circ = 0.0625 \times 360^\circ = 22.5^\circ$

The angles for the pie chart sectors are:

• Graphic: $135^\circ$
• Ghanaian Times: $90^\circ$
• Mirror: $67.5^\circ$
• Daily Guide: $45^\circ$
• Free Press: $22.5^\circ$ (You would use these angles to draw the respective sectors in a circle.)

Question 5:

i) Find angle $y$ representing savings for the month.

The sum of all angles in a circle is $360^\circ$.

The angle $y$ representing savings is $\boxed{36^\circ}$.

ii) What's the man's salary for the month?

We know that Gh¢180.00 was spent on rent, which corresponds to an angle of $72^\circ$.
Let $S$ be the total salary.

The man's salary for the month is $\boxed{\text{Gh¢900.00}}$.

iii) By how much does expenditure on others exceed that on clothing.

The angle for "Others" is $84^\circ$.

The angle for "Clothing" is $60^\circ$.

The expenditure on others exceeds that on clothing by $\boxed{\text{Gh¢60.00}}$.
