Question 1



Q1) Express as rupees using decimals.

(a) 5 paise (B) 75 paise (c) 20 paise

(d) 50 rupees 90 paise (E) 725 paise

Solution 1:

(a) Re. 1 = 100 paisa

1 paisa = Re. \frac{1}{100}1001

5 paisa = Re. 5\times\frac{1}{100}=\ \frac{5}{100}=Re.\ 0.055×1001= 1005=Re. 0.05

(b) Re. 1 = 100 paisa

1 paisa = Re. \frac{1}{100}1001

75 paisa = 75\times\frac{1}{100}=\ \frac{75}{100}=Re.\ 0.7575×1001= 10075=Re. 0.75

(c) Re. 1 = 100 paisa

1 paisa = Re. \frac{1}{100}1001

20 paisa = 20\times\frac{1}{100}=\ \frac{20}{100}=Re.\ 0.2020×1001= 10020=Re. 0.20

(d) Re. 1 = 100 paisa

1 paisa = Re. \frac{1}{100}1001

50 rupees 90 paisa = 50\ +\ 90\times\frac{1}{100}=50+\frac{90}{100}=50+0.90=\ Rs.\ 50.9050 + 90×1001=50+10090=50+0.90= Rs. 50.90

(c) Re. 1 = 100 paisa

1 paisa = Re. \frac{1}{100}1001

725 paise = 725\times\frac{1}{100}=\frac{725}{100}=Rs.\ 7.25725×1001=100725=Rs. 7.25
