In conversion of money we will learn to convert the amount from rupees to paisa and from paisa to rupees.
Conversion from rupees to paisa and from paisa to rupees is based on the basic fact that Re. 1.00 = 100 paisa and 100 paisa = Re. 1.00
From this fact we find that
Rs. 1.00 = 100 paisa
Rs. 2.00 = 200 paisa Rs. 5.00 = 500 paisa
Rs. 10.00 = 1000 paisa |
100 paisa = Re. 1.00 200 paisa = Re. 2.00 500 paisa = Re. 5.00
1000 paisa = Re. 10.00 |
We know that Rs. 1 = 100 p. So, to convert rupees into paise we multiply the number of rupees by 100.
Rs. 7 = 7 × 100 = 700 paise or 7 p
Rs. 9 = 9 × 100 = 900 paise or 9 p
To convert rupees and paise into paise, we convert rupees into paise and add paise.
Rs. 8 and 50 paise = 8 × 100 + 50
= 800 + 50
= 850 paise or 850 p
Changing Rupees to Paisa and Vice Versa:
100 paisa is same as Rs. 1.
I: To change rupees to paisa, put two zeros at the end of number.
For example:
Rs. 3 = 3 x 100 = 300 p
Rs. 10 = 10 x 100 = 1000 p
II: To change paisa to rupees, put a point after the two digits from right.
For example:
684 p = Rs. 6.84
4500 p = Rs. 45.00
38 p = Rs. 0.38
III: To change rupees and paisa to only paisa, remove the point and write the numbers together.
For example:
Rs. 9.50 = Rs. 9 + 50 p = 900 p + 50 p = 950 p
Rs. 10.98 = 1098 paisa
Worked-out Examples on Conversion of Money:
1. Convert the following:
(i) Rs. 3.50 into paise
Solution:
Rs. 3.50
= Rs. 3.00 + 50 paise
= (3 × 100) paise + 50 paise
= 300 paise + 50 paise
= 350 paise
(Thus, to convert rupees and paise into paise, we remove the point (.) and symbol Re. or Rs. and write Paise on the right of the number so obtained)
For example:
Rs. 7.25 = 725 paise
Rs. 11.85 = 1185 paise
(ii) 815 paise into rupees
Solution:
815 paise
= 800 paise + 15 paise
= (8 × 100) paise + 15 paise
= Rs. 8 + 15 paise
= Rs. 8.15
(Thus, to convert paise into rupees and paise, the point called decimal point is placed after the two digits from the right of the number showing paise and then Re. or Rs. is written on the extreme left)
For example:
450 paise 1375 paise 75 paise
47 paise 605 paise
745 paise |
= Rs. 4.5 = Rs. 13.75 = Re. 0.75 = Rs. 0.47
= Rs. 6.05 = Rs. 7.45 |
