Correct Answer :

Option E

576

Solution :

The correct answer is 576.

Step 1: Approximate the individual terms in the given expression.

139.98% of 250.03140% of 250=140100×250=350
540.0917.9854018=30
(20.08)2202=400
3.984

Step 2: Substitute the approximated values back into the expression.

350+30+?-4=404

380+?-4=404

Step 3: Solve for the unknown value (?).

?-4=404-380
?-4=24

Squaring both sides of the equation:

?-4=242
?-4=576
?=576+4=580576

Hence, the approximate value that comes in place of the question mark is 576.
