Answer:
The number of apple for 1 cup of water is 1.5 apples

Given as :
The number of cups of water = 91 cups
The number of apples for every 91 cups of water = 140
Let The number of apple for 1 cup of water = n
<u>Now, From unitary method :</u>
∵ For every 91 cups of water , the number of apple needed = 140
∴ For every 1 cup of water , the number of apple needed = 
I.e n = 
or, n = 1.5 apples
The number of apple for 1 cup of water = n = 1.5 apples
