- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
What approximate value should replace the question mark?
(599.90 Ă· 12.02) + (179.98 Ă· 6.00) = ?% of 200.0 - 20.3
[(343) 1/3 Ă· {(12.001)2 Ă— (1 Ă· (4.03 Ă— 2.97) 2 )}] = ?
(98.03 + 186.98) ÷ 19.211 = 89.9 – 20.23% of ?
16.99% of 399.99 Ă· 17.17 = ? Ă· 15.15
(8.86)² × (15.01)² ÷ √624.99 = 9?
(21.02 Ă— 5.83 Ă— 12.03 Ă· 6.99 of 4.03) + 31.93% of 50.03 = ?
What approximate value should replace the question mark?
30.02% of 400.03 + ?% of 600.05 = 300.01
65.22 of 359.98% + 459.99 Ă· 23.18 = ?
