A fruit vendor sell 4 lemon for rs 16 and 11 bananas for rs 33 , Which cost more 10 lemon or 10 bananas and by how much ?

Cost of $4$ lemon $=16$

Cost of $1$ lemon $=\frac{16}{4}=4$

Cost of $10$ lemon $=40$Rs

Cost of $11$ banana $=33$

Cost of $1$banana $\frac{33}{11}=3$

Cost of $10$ banana $=3\times 10=30$ Rs

Thus $10$ lemon cost more than $10$ banana by Rs $10$
