What approximate value should come in place of question mark (?) in the following questions ?(You are not expected to calculate the exact value)

Question 56

$$783.559+49.0937\times31.679-58.591=?$$

Solution

We first approximate for ease of calculation.

783.559~784, 49.037~49, 31.6759~32 and 58.591~59

Now following the BODMAS rule, we first do multiplication.

49*32=1568,

784 + 1568 - 59 = 2293 to which 2280 is the closest option

Hence, option E is correct
