At a rally attended by 200 people, 30% were Fantes, 25% were Asantes, 20% were Gas, 20% were Nzemas and the rest were Dagombas. a. How many Dagombas were at the rally? b. What percentage were Dagombas? c. Draw a pie chart to illustrate data.

Total people at the rally: 252
Nyesmas: 202

Step 1 (Part a): Find the number of Dagombas.

Number of Dagombas = Total people - Nyesmas
$252 - 202 = 50$

There were 50 Dagombas at the rally.

50

Step 2 (Part b): Find the percentage of Dagombas.

Percentage of Dagombas = $\dfrac{Number of Dagombas}{Total people} \times 100\%$
$=\dfrac{50}{252} \times 100\%$

First, simplify the fraction:
$\dfrac{50 \div 2}{252 \div 2} = \dfrac{25}{126}$

Now calculate:
$\dfrac{25}{126} \approx 0.1984$
$0.1984 \times 100\% = 19.84\%$

Approximately 19.84% of the people were Dagombas.

19.84%

Step 3 (Part c): Pie chart data.

Total angle = $360^\circ$

Angle for Nyesmas:
$\dfrac{202}{252} \times 360^\circ = \dfrac{101}{126} \times 360^\circ \approx 288.57^\circ$

Angle for Dagombas:
$\dfrac{50}{252} \times 360^\circ = \dfrac{25}{126} \times 360^\circ \approx 71.43^\circ$

Draw a circle.

• Shade $\approx 288.57^\circ$ for Nyesmas (major sector).
• Shade $\approx 71.43^\circ$ for Dagombas (minor sector).
  Label the sectors with names and percentages (Nyesmas: 80.16%, Dagombas: 19.84%).
