Correct Answer :

Option D

1610

Solution :

The correct option is 1610.


To find the approximate value that replaces the question mark (?), we can round off the numbers in the given expression to their nearest whole numbers for easier calculation:


1. 729.1437293

Since 93=729, we get:

7293=9


2. 11.013113

Calculating 113:

113=1331


3. 60.24% of 449.8660% of 450

Calculating 60% of 450:

60100×450=270


Now, substitute these approximate values back into the main expression:

?9+1331+270


Adding the numbers together:

?1340+270=1610


Hence, the approximate value that should replace the question mark is 1610.
