Direction (110): What approximate value should come in place of question mark (?) in the following questions?
31.95^2 – 12.05^2 + (1987.25 + 21.85) ÷ ? = 900
Correct
Correct Answer is: E)
31.95^2 – 12.05^2 + (1987.25 + 21.85) ÷ ? = 900
(32 × 32) – (12 × 12) + (2009) ÷ ? = 900
880 + (2009) ÷ ? = 900
? = 2009 / 20 = 100.4
? ≈ 100
