Question

The ratio of strawberry and banana batter is 2:3. We need 30 cups of batter total. What percent of the cake is banana

Answer 1

60%

Explanation:

Given that,

the ratio of strawberry and banana batter is 2 : 3

there is total 30 cups of batter

To find,

percent of the cake is banana in 30 cups of batter

Suppose x is the number of cups of banana in the batter

3 / (2+3) = x / 30

3 / 5 = x / 30

x = 3*30 / 5

x = 90 / 5

x = 18

So there are 18 cups of banana in 30 cups of batter

percentage of banana in cake = 18/30 * 100

= 60%
