The logic followed here is: First number = 2 X Second number - 3 32 : 16 → 2 X 16 - 3 = 32 – 3 = 29. 55 : 29 → 2 X 29 - 3 = 58 – 3 = 55. 39 : 21 → 2 X 21 - 3 = 42 – 3 = 39. 73 : 38 → 2 X 38 - 3 = 76 – 3 = 73.
412 - 352 + ? = 113 - 192
Simplify the following questions:
(11) 8.5 × (121) 5.5 ÷ (1331) 5.5 = (11) ?
...72 x 60 x 22 x 32 =?
525 ÷ 21 x 28 – 853 + 264 = ?
240 × 2.5 + 65 × 2/13 = ?2 - √225
22% of 560 + 34% of 2160 × 5/12 =? + 16% of 920
118 × 6 + 13 + 83 = ?
√ (573 – 819 + 775) = ? ÷ 3
144% of 200 + 11% of 900 + 10% of 20 =?
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
