Question

The price of bananas is Rs.30 a dozen. Aditya can buy 12 dozen bananas with the amount of money he has. If the price of bananas is increased by Rs.10 a dozen, how many dozen bananas can Aditya buy ?

Answer 1

Price of $1$ dozen banana $=Rs30$.

Price of $12$ dozen banana $=Rs30\times 12=Rs360$.

So Aditya has Rs$360$ with him to buy bananas.

Now if the price is increased by Rs$10$

New price of $1$ dozen banana $=Rs40$

Total money Aditya has $=Rs360$

No. of dozen he can buy $=\frac{TotalMoney}{Priceof1dozen}=\frac{360}{40}=9$

Aditya can buy $9$ dozen bananas with the money he has.
