Ravi initially had $x$ fruits. Now, he bought $y$ fruits and sold $z$ fruits to his friend. The number of fruits he has is .

The correct option is C $x+(y-z)$
Ravi initially had $x$ fruits. After buying $y$ fruits, he had $x+y$ fruits. Then, he sold $z$ fruits to his friend. So, now he has $(x+y)-z$ fruits.

But according to unchanging relations, $(x+y)-z=x+(y-z).$
Hence, he has $x+(y-z)$ fruits now.
