Question

The preference of protein shakes obtained for 100 kids in a survey is given below.​ The kids preferring Horlicks are the ……………….. of the kids preferring Bournvita . ​

• A. One-fourth
• B. half
• C. twice
• D. one-third

Answer 1

The correct option is B half

The proportion of kids preferring Horlicks = Area of central angle covered by Horlicks in pie-chart,​
​
And the proportion of kids preferring Bournvita = Area or central angle covered by Bournvita in pie chart​
​
From the pie chart, we can see that quarter of the area of circle (or 90 degrees) is covered by Horlicks and half of the area of circle(or 180 degrees) is covered by Bournvita​
​
Thus, Proportion of kids preferring Horlicks ​
Proportion of kids preferring Bournvita​
​
= Area of angle covered by Horlicks ​
Area of angle covered by Bournvita​
$\frac{\frac{1}{4}}{\frac{1}{2}}or\frac{90}{180}=\frac{1}{2}$that is option D (half)
