Question

Pooja has enough money to buy $36$ oranges at the rate of $Rs4.50$ per orange. How many oranges she can buy if the price of each orange is increased by $90$ paise?

Answer 1

Given,

Cost of one orange = $₹4.50$

Cost of $36$ oranges = $₹4.50\times 36=₹162$

So, new price of one orange = $₹4.50+0.90=₹5.40$

With $₹162$,

the number of oranges that can be bought = $\frac{162}{5.40}=30$

$\therefore$ The number of oranges that is available are $30$.
