    Question

    The sum of 440 and 560 using front – end estimation is ______.

    1. 400
    2. 1000
    3. 700
    4. 900

    Hint:

    We have to find the sum of 440 and 560 using front end estimation. In front end estimation firstly we will round off the numbers i.e. 440 and 560. The number obtained after rounding off will be added to get the required number.

    The correct answer is: 1000

      Rounding the number 440 =400
      Rounding the number 560= 600
      Sum of 400 and 600
      = 400+600
      =1000
      So, the sum of 440 and 560 using front end estimation is 1000.
