Question

Siri has enough money to buy $5kg$ of potatoes at the price of $Rs8perkg$. How much can she buy for the same amount if the price is increased to $Rs10perkg$?

Answer 1

According to the question,

Total amount Siri had initially $=5\times 8=Rs.40$

Now,

New price of potato $=Rs.10$ per kg

So, he can buy with $Rs.40$ $=\frac{40}{10}=4kg$ potatoes

Hence, this is the required result.
