Word Problems on Addition of Money

Worked-out examples on addition of money:

1. Add Rs. 27.75 and Rs. 40.08

Solution:

Method 1 (with conversion into paise):

Amounts to be added are converted into paise.

Rs. 27.75 = 2700 paise + 75 paise = 2775 paise

Rs. 40.08 = 4000 paise + 08 paise = 4008 paise

Now, sum

Rs. 27.75 = 2775 Paise

+ Rs. 40.08 = + 4008 Paise

6783 Paise

Therefore, sum of Rs. 27.75 and Rs. 40.08 = Rs. 67.83

Method 2 (without conversion into paise):

Here rupees and paise are arranged in different columns and then added like ordinary numbers.

Rs Paise

Rs. 27.75 = 27 75

+ Rs. 40.08 = + 40 08

67 83

Therefore, sum of Rs. 27.75 + Rs. 40.08 = Rs. 67.83

2. Add Rs. 125.65, Rs. 38.48 and Rs. 110.05

Solution:

Method 1 (with conversion into paise):

Amounts to be added are converted into paise.

Rs. 125.65 = 12500 paise + 65 paise = 12565 paise

Rs. 38.48 = 3800 paise + 48 paise = 3848 paise

Rs. 110.05 = 11000 paise + 05 paise = 11005 paise

Now, sum

Rs. 125.65 = 12565 Paise

Rs. 38.48 = 3848 Paise

+ Rs. 110.05 = + 11005 Paise

27418 Paise

Therefore, sum of 125.65, Rs. 38.48 and Rs. 110.05 = Rs. 274.18

Method 2 (without conversion into paise):

Here rupees and paise are arranged in different columns and then added like ordinary numbers.

Rs. Paise

125 65

38 48

+ 110 05

274 18

Therefore, sum of 125.65 + Rs. 38.48 + Rs. 110.05 = Rs. 274.18
