Question

50% of all the cakes jenny baked that week were party cakes, 1/5 were fruits cake and the remainder were sponge cake. what is the percentage of the sponge cakes

Answer 1

30%
1/5 is 0.2, or 20%. So 50%+20% = 70%. The remainder is 30%

Answer 2

30% sponge cakes.

Explanation:

We have been given that 50% of all the cakes jenny baked that week were party cakes, 1/5 were fruits cake.

Let us convert 1/5 into percentage as:

`(1)/(5)* 100\%`

`0.2* 100\%`

`20\%`

Therefore, 20% of cakes are fruit cake.

Now, we will find remainder by subtracting 20 plus 50 percent from 100 percent as:

`\text{Remainder}=100\%-(50\%+20\%)`

`\text{Remainder}=100\%-70\%`

`\text{Remainder}=30\%`

Therefore, the percentage of the sponge cakes is 30%.
