 example 1:  Add `438.90, `185.65 and `155.85.  1  2  2  1  practice time 12b
 Solution:   Arrange the given amounts in columns and then   ` 4 3 8 . 9 0

 add as shown alongside.   ` 1 8 5 . 6 5    1.  Add the following:
          Hence, the required sum = ` 780.40.  + ` 1 5 5 . 8 5  (a)  `  7 5 6 . 5 0  (b)  `  5 3 3 . 5 0  (c)  `  3 0 3 4 . 7 5

 example 2: Subtract `197.85 from `321.  ` 7 8 0 . 4 0  `  2 2 9 . 6 5  `  3 5 4 . 5 6      `     5 0 3 2 . 2 5

 Solution:   Arrange the given amounts in columns. As there   11 10  9  + `  2 3 1 . 9 0  + `  2 3 3 . 4 4  + `  1 3 2 3 . 0 0

          Hence, the required difference = `123.15.  ` 1 2 3 . 1 5  (a)  `3973.65, `1523.45, `256.54 and `1360.56

 money did he spend in all?

 Solution:          (a)    ` 7 4 5 . 2 0             (b)    ` 8 5 6 . 4 0            (c)    ` 4 5 2 . 0 0
                         – ` 3 4 6 . 5 6                  – ` 3 5 2 . 7 5                 – ` 3 1 2 . 1 6
 1  1  1  2  1

 Money spent on a pair of shoes  =  ` 2 2 5 6 . 7 5
 Money spent on a shirt  =  ` 1 3 5 3 . 2 5    4.  Write the following in columns and subtract.

 Money spent on a pair of trousers =  ` 1 7 3 4 . 5 0  (a)  `486.00 from `2000  (b)  `3267.75 from `7500.25
 Money spent on a tie  = + `  5 0 0 . 7 5  (c)  `2745 from `6000      (d)  `2045.68 from `4054.99
 Total amount spent on all the items =  ` 5 8 4 5 . 2 5    5.  Siya bought a pencil for  `5.40,  an  eraser  for  `4.65  and  a geometry box  for

          Hence, Mr Gupta spent `5845.25 in all.  `58.60. What is the total amount she paid to the shopkeeper?
