Question
In a circle two chords AB and CD intersect at O, if AO =
4, BO = 3 and CO is one fourth of OD then Find OD?Solution

30.05% of 149.97 + ? X 8.88 = (39.95 + 12.012 - 13.0322)2Â
What approximate value will replace the question mark (?) in the following?
? –...
What approximate value should come in the place of (?) in the following questions?
?3 -18.32 * 40.24 ÷ √399 = 200.79 + 105.78
...1449.98 ÷ 50.48 × 10.12 = ? × 2.16
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99Â
156.76 + 14.08² + ?³ = √625.12 * 26.87
(1440.13 ÷ 31.77) × (√168.69 + 16) - (24.87% of 719.99) = ?
24.45% of 14.99% of 14999.78 + 159.80 = ?% of 1999.78
20.57 ×28.04 ÷ ? + 254 = 429.06
(23.99)2 – (17.99)2 + (1378.98 + 44.99) ÷ ? = 608
