Answer:
Cost of 7 packet is 63
so cost of 1 packet will be 63/7 that is 9 rupees
so cost of 9 such packets will be 9*9 that is 81.
₹81 is the answer
Answer:
81 $
Step-by-step explanation:
7 balloons cost = $ 63
1 balloon costs = $ (63/7) = $ 9
9 such balloons cost = $ (9 × 9)
= 81 $
This is a unitary method, if you wanna know how to make it work then go for the following steps:
Example:
if the question says something like 3 pencils cost 5, find the cost of 6 pencils
Here, the quantity we need to find out is the cost! So the cost will occur on the right side of the equation.
Something like:
no. of balloons = cost of balloons
Example:
Taking the same example as above
the next step will be:
cost of 1 balloon = cost of balloons/ number of balloons.
Example:
same example as above:
cost of 6 balloons = 6 × cost of 1 balloon.
That will get you the answer.
