Multiplication and division of Money

Multiplication and division of money are similar to normal multiplication and division.
Let us see a few examples.

example 3. If one pen costs `35, find the cost of 8 pens.

Solution.

The cost of one pen = `35
Number of pens = 8 3 5

So, the cost of 8 pens = `35 × 8 × 8 ` 35
2 8 0
= `280

example 4. Golu bought 6 lollipops and gave a `50 note to the shopkeeper. If one
lollipop costs `5, how much money would the shopkeeper return?

Solution.

Cost of one lollipop = `5

So, cost of 6 lollipops = `5 × 6 = `30

Golu gave a `50 note. The shopkeeper would return = `50 – `30 = `20.

example 5. One notebook costs `18. How many notebooks can you
buy with `612?

Solution. 3 4

The cost of one notebook = `18 18 6 1 2

Total amount = `612 –5 4
Number of notebooks that can be bought with the given amount = 7 2
612 ÷ 18 = 34 –7 2

Thus, 34 notebooks can be bought with `612. 0
