Question
√2024.84 + (24.86% of 1999.81) - (3/8 of 800.15) =
? What approximate value should come in place of (?) in the following questions (Note: You are not expected to calculate the exact value.)Solution
√2024.84 + (24.86% of 1999.81) - (3/8 of 800.15) = ? √2025 + (25% of 2000) - (3/8 of 800) √2025 = 45. 25% of 2000 = (25/100) × 2000 = 500. 3/8 of 800 = (3/8) × 800 = 300. Adding and subtracting: 45 + 500 - 300 = 245. Correct answer: c
(124.901) × (11.93) + 219.95 = ? + 114.891 × 13.90
1784.04 - 483.98 + 464.98 ÷ 15.06 = ?3
44.89% of 600.25 + (29.98 × 5.67) + (√1940 – 10.29) = ?2
124% of 620.99 + 11.65% of 1279.23 = ?
√1600.13 x √4355.99 ÷ 329.98 + 1223.23 = ?
(56.03 + 112.98) ÷ 13.211 = 89.9 – 25.23% of ?
456 x 99.999 + 654 = ?
[(√2024.85 ÷ 3.01) + (35.76 ÷ 11.92)]² × (3/4 of 39.99) = ?
A boat can travel 30 km upstream and 45 km downstream in 6 hours. Find the speed of the boat in still water if the speed of the stream is 4 km/h.
? + 163.99 – 103.01 = 24.01 × 6.98
