The price of a sofa set is ₹2540.80. Find the total cost of 195 such sofa sets.

The weight of a box is 146 kg 68 g. Find the weight of 365 such boxes.

Answer :

To solve these problems, we need to perform multiplication for both the price of the sofa sets and the weight of the boxes.

  1. Calculating the Total Cost of 195 Sofa Sets:

    The cost of one sofa set is ₹2540.80. To find the total cost of 195 sofa sets, we multiply the price of one sofa set by the number of sofa sets:

    [tex]\text{Total Cost} = 2540.80 \times 195[/tex]

    To make the calculation easier, you can first multiply without the decimal:

    [tex]254080 \times 195 = 49545600[/tex]

    Then, place the decimal point back in the result, considering two decimal places:

    [tex]\text{Total Cost} = 495456.00[/tex]

    So, the total cost for 195 sofa sets is ₹495,456.

  2. Calculating the Total Weight of 365 Boxes:

    The weight of one box is 146 kg and 68 g. First, convert the weight into kilograms since both need to be in the same unit.

    1 kilogram = 1000 grams,

    68 g = 0.068 kg.

    Therefore, the weight of one box in kilograms is:

    [tex]146 + 0.068 = 146.068 \text{ kg}[/tex]

    Now, multiply the weight of one box by the number of boxes:

    [tex]\text{Total Weight} = 146.068 \times 365[/tex]

    Perform the multiplication:

    [tex]146.068 \times 365 = 53215.82[/tex]

    Therefore, the total weight of 365 boxes is 53,215.82 kg.

By following these steps, you can solve these problems, calculating the total cost of the sofa sets and the total weight of the boxes accurately.
