What approximate value will come in place of question mark (?) in the following question ?

 (49.001)²  = ?

  • A.2500
  • B.2400
  • C.2600
  • D.2300

Answer: B

Correct answer: 2400

\( 49^2 = 2401 \), and 49.001 differs from 49 by so little that the square is still about 2401. To the nearest figure offered that is 2400.
