(2520.33 ÷ 41.67) × (√168.88 + √80.78) - 10% of 1499.85 = ?
(3374 ÷ 125.13)1/3 + (362 ÷ 11) = ?2 – 27.79
What approximate value will replace the question mark (?) in the following?
? = 1...
20.05% of 150.05 – 12.15% of 99.99 × 2.02 = ?
(16.16 × 31.98) + 14.15% of 249.99 = ? + 99.34
583.9 + 1519.98 - 445.21 = 1150.011 + ?
What will be the approximate value of the following questions.
(74.75% of 600.29 – 44.85% of 399.99) × (√224.95 ÷ 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....
(9.013 – 15.04) = ? + 9.98% of 5399.98
50.098% of 7000.072 ÷ 69.6969 + 75.093 of 15.98 = ? × 4.983
