Answer 2

Calculations for Election Results:

To calculate the percentage of votes received by the losing candidate, we can use the ratio of 3:2, where the winning candidate received 3 parts and the losing candidate received 2 parts.

The total parts can be calculated by adding the parts received by both candidates, which is 3 + 2 = 5.

To find the percentage of votes received by the losing candidate, we can use the formula: \[ \text{Percentage} = \left( \frac{\text{Parts received by losing candidate}}{\text{Total parts}} \right) \times 100 \]

Substituting the values, we get: \[ \text{Percentage} = \left( \frac{2}{5} \right) \times 100 = 40\% \]

The losing candidate received 40% of the votes.

Percentage of Grape Juice in Fruit Drink:

The ratio of apple juice to grape juice in the fruit drink is 13:7.

To find the percentage of grape juice in the fruit drink, we can use the formula: \[ \text{Percentage of grape juice} = \left( \frac{\text{Parts of grape juice}}{\text{Total parts}} \right) \times 100 \]

Substituting the values, we get: \[ \text{Percentage of grape juice} = \left( \frac{7}{13+7} \right) \times 100 \approx 35.00\% \]

The grape juice makes up approximately 35% of the fruit drink.
