Let’s solve each addition problem step by step. We’re adding money amounts in Rupees (Rs), so we’ll add the rupees and paise separately, just like adding decimals.
Remember:
- The number before the dot is Rupees.
- The number after the dot is Paise (like cents).
- Always line up the decimal points when adding!
---
a. Rs 45.50 + Rs 30.20
Add rupees: 45 + 30 = 75
Add paise: 50 + 20 = 70
→
Rs 75.70
---
b. Rs 74.60 + Rs 96.10
Add rupees: 74 + 96 = 170
Add paise: 60 + 10 = 70
→
Rs 170.70
---
c. Rs 10.00 + Rs 7.00
Add rupees: 10 + 7 = 17
Add paise: 00 + 00 = 00
→
Rs 17.00
---
d. Rs 50.00 + Rs 27.80
Add rupees: 50 + 27 = 77
Add paise: 00 + 80 = 80
→
Rs 77.80
---
e. Rs 69.74 + Rs 98.43
Add rupees: 69 + 98 = 167
Add paise: 74 + 43 = 117 → That’s more than 100! So carry over 1 rupee.
117 paise = 1 rupee and 17 paise
So total rupees: 167 + 1 = 168
Paise left: 17
→
Rs 168.17
*(Double-check: 69.74 + 98.43 — let’s add vertically:
69.74
+98.43
=168.17 ✔️)*
---
f. Rs 39.40 + Rs 27.21
Add rupees: 39 + 27 = 66
Add paise: 40 + 21 = 61
→
Rs 66.61
*(Check: 39.40 + 27.21 = 66.61 ✔️)*
---
Final Answer:
a. Rs 75.70
b. Rs 170.70
c. Rs 17.00
d. Rs 77.80
e. Rs 168.17
f. Rs 66.61
