A238.7863

B248.0863

C258.0783

D249.0863

Answer:

B. 248.0863

Read Explanation:

Calculation: 223.3 + 22.33 + 2.233 + 0.2233 = ? ⇒ ? = 248.0863 ∴ ? = 248.0863 Alternate Method: We can also solve this question by appending zeros after the decimal point till the number of digits, which has the highest number of digits after the decimal point among all the numbers, So from the given equation, 223.3 + 22.33 + 2.233 + 0.2233 = ? We have, the highest number of digits after the decimal point = 4 So, we append each of the number to four digits after the decimal point, by adding the necessary number of zeroes, as follows: ⇒ 223.3000 + 22.3300 + 2.2330 + 0.2233 = ? ⇒ ? = 248.0863 ∴ ? = 248.0863 Important Point: The alternate method is much more accurate, because it will ensure no mistake in calculations after the decimal point .
