We will discuss here about coins and currency notes. In our daily life we purchase things from the shop and pay money to the shopkeeper. We are already aware of the following coins and notes. Coins of 1 paise, 2 paise, 5 paise are not available and that of 10 paise, 20 paise, 25 paise, 50 paise are less in circulation. Notes of Re 1 and Rs 2 are also less in circulation. 1 rupee is equal to 100 paise. We write p for paise. p is written after the amount.
Rupee is a larger unit of money than paise.
We use ‘p’ to write paise.
We use ‘Re’ to write rupee.
We use ‘Rs’ to write rupees.
We use dot (.) to separate rupees and paise.
Figure on the left of the dot represents rupees.
Figure on the right of the dot represents paise.
Number of paise is written as 2-digit number.
(i) If the amount of money consists of paise only we put
zero before the dot (.) to indicate that there are no rupees. For example, 75
paise is written in figures as Re 0.75 or 75 p.
(ii) If the number of paise has one digit, we put zero before it to make a two digit number. For example, 5 paise in figure is written as Re 0.05 or 5 p.
We must know that:
100 paise = Re 1
Two 50 paise = Re 1
Four 25 paise = Re 1
Five 20 paise = Re 1
Ten 10 paise = Re 1
