Estimation of Solutions in Grade VI

In this session we are going to discuss Estimation of Solutions. Before we proceed for any project we need to find the estimated budget for the project to be attained. This is done by rounding the values to nearest tens, hundreds or thousands.  Suppose we go to buy some fruits and other purchase items. We make a rough budget of the articles to be purchased and take Rs 200 in my purse. This is called estimating solutions. Now when we buy the fruits, the seller tells the following costs:  Apples of Rs 84.00, Bananas of Rs 35 and grapes of Rs 18.
  The shopkeeper gives us the bill of Rs 84.00
                                                          Rs 35.00
                                                    +   Rs 18.00
                                                        _____________
                                                             137.00
We simply round off the figure to nearest tens and pay Rs 140 to him. Another way to make the payment will be to round off the above figure in nearest hundred and pay Rs 150.00 estimation of solutions is done in order to make any project a success, may it be a window shopping, budgeting for the parties big or small about how many expected guest will be attending the party or even organizing big projects.
In Grade VI We follow the following methods for estimating solutions:
To round off the value to nearest tens, we see the ones place digit, if it is less than 5, we make ones place 0. If it is greater than 5 we add 1 to tens place and make ones place 0. E.g.:
      47 round off to tens becomes 50
     32  round off  to tens becomes 30
    65 round off to tens becomes 70
In the next topic we are going to discuss Percentages
