If 15 oranges costs Rs. 45, the cost of one orange would be 45/15 (or 45 ÷ 15)
First, divid 45 by 15 to find the value of one orange.
45 ÷ 15 = 3
Now that we know one orange costs Rs. 3, we can find the value of 81 oranges.
81 x 3 = 243
So 81 oranges is equal to Rs. 243.
Hope this helps you understand how to get to the answer! <3
