Hi buddy :

$\\ \large \sf \: relevant \: \: answer : )$

Pie Chart is in a form of circle

$\\ \large \tt \: angle \: \: sum \: \: of \: circle = 360 \degree$

Given :

(Blood Groups)

• Group A = 90°
• Group B = 144°
• Group AB = 54°
• Group O = 72

$\\ \large \sf \: percentage$

$\\ \large \boxed{ \sf = \frac{measure \: \: of \: \: angle \: \: of \: \: a \: \: particular \: \: group}{total \: \: measure} \times 100}$

For Blood Group A

(90°)

$\\ \large \tt \implies \: percentage = \frac{90 \degree}{360 \degree} \times 100 \\ \\ \\ \large \tt \implies \: percentage = \frac{100}{4} \\ \\ \\ \large \sf \therefore \: percentage = 25\%$

For Blood Group B

(144°)

$\\ \large \tt \implies \: percentage = \frac{144 \degree}{360 \degree} \times 100 \\ \\ \\ \large \tt \implies \: percentage = 4 \times 10 \\ \\ \\ \large \sf \therefore \: percentage = 40\%$

For Blood Group AB

(54°)

$\\ \large \tt \implies \: percentage = \frac{54 \degree}{360 \degree} \times 100 \\ \\ \\ \large \tt \implies \: percentage = 3\times 5 \\ \\ \\ \large \sf \therefore \: percentage = 15\%$

For Blood Group O

(72°)

$\\ \large \tt \implies \: percentage = \frac{72 \degree}{360 \degree} \times 100 \\ \\ \\ \large \tt \implies \: percentage = 2\times 10 \\ \\ \\ \large \sf \therefore \: percentage = 20\%$

Answers :

• Out of 100%

➢ Blood Group A = 25%

➢ Blood Group B = 40%

➢ Blood Group AB = 15%

➢ Blood Group O = 20%
