What approximate value will come in place of the question mark(?) in the given questions ? (You are not expected to calculate the exact value
(42.11 $$\times$$ 5.006) - $$\sqrt{7} \times$$ 15.08 = ?
Since it is sufficient to find the approximate value, round off the values.
42.11 $$\times$$ 5.006 = 42 $$\times$$ 5 $$\approx$$ 210
$$\sqrt{7} $$ lies between 2 and 3.The actual value of $$\sqrt{7}$$ = 2.645.
$$\sqrt{7} \times$$ 15.008 = $$\sqrt{7} \times$$ 15 $$\approx$$ 39.
210-39 = 171
The nearest Option is Option B.
Hence Option B is the correct answer.
