Question

If $16$ oranges cost Rs.$48$, how many oranges can be bought for Rs. $63$?

Answer 1

Let $x$ oranges be bought for $Rs.63$.

In $Rs.48$, the number of oranges that can be bought is $16$.

In $Re.1$, the number of oranges that can be bought is $\frac{16}{48}$

In $Rs.63$, the number of oranges that can be bought is $\frac{16}{48}\times 63=21$

Hence, $21$ oranges can be bought.
