Detailed Solution
Download Solution PDFGiven:
12.21 + 0.69 - √99.90 + (5.90 - 3.90) = x
Formula Used:
Approximation of numbers to the nearest integer for calculation.
Calculations:
⇒ 12.21 ≈ 12
⇒ 0.69 ≈ 1
⇒ √99.90 ≈ √100 = 10
⇒ (5.90 - 3.90) = 2.00 ≈ 2
Substituting approximate values into the equation:
⇒ x = 12 + 1 - 10 + 2
⇒ x = 13 - 10 + 2
⇒ x = 3 + 2 = 5
Hence, the correct answer is "Option 4".
