What approximate value should come in place of the question mark (?) in the following questions ? (Note : You are not expected to calculate the exact value.)
7777.009 - 596.999 -89.989 = ?
Option:C
As the options provided do not have any decimal places, we will use approximation to solve this question and find the nearest value.
So, the question now becomes 7777 - 597 - 90
i.e.7777 - 687
which gives 7090.
(Alternatively, one can notice that the options are not very close to each other. So, we can further approximate (7777 - 687) ∼ (7800 - 700) ∼ 7100. We can clearly see that the nearest value is 7090.)
