What approximate value will come in place of the question mark (?) in the following question? (You are not expected to calculate the exact value.) In an industrial filtration study, the flow efficiency is modeled as: (41.98314.95) × (45.02252.05) × ? = 15.01

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.)24.89% of ? + 75.15% of 399.78 = 16 of 2499.68%

What approximate value will come in place of the question mark (?) in the following question? (13.13)2 + (15.89)2 - (12.12)2 ÷ 9.09 = ?
