Rupees - Paisa Conversion:

We know that ∴Conversion
100 paisa = Re. 1.00
100 paisa = Re 1
∴ 200 paisa = Rs. 2.00
We multiply given rupees by 100 to
convert into paisa.

Re. 1 = 100 paisa
∴ Rs 5 = 5 × 100 paisa
= 500 paisa

6. Complete the following (one is done for you):

Rs. 5 = 5 × Re. 1 Rs. 7 = × Re. 1
= 5 × 100 paisa = × paisa
= 500 paisa = paisa
∴ Rs. 5 = 500 paisa ∴ Rs. 7 = paisa

Rs. 3 = × Re. 1 Rs. 4 = × Re. 1
= × paisa = × paisa
= paisa = paisa
∴ Rs. 3 = paisa ∴ Rs. 4 = paisa

7. Convert the following rupees into paisa (One is done for you).

Rs. 3 and 20 paisa = Rs. 3 + 20 p
= 3 × 100p + 20 p
= 300p + 20 p
∴ Rs. 3 and 20 p = 320p

I have Rs. 2. How much paisa do I have?
Re. 1 = 100 p
∴ Rs. 2 = 2 × 100 p = 200 p
∴ I have 200 paisa.
