Question
Select the option that is related to the third number
in the same way as the second number is related to the first number. 42 : 1769 :: 34 : ?Solution
The pattern followed here is: (First Number)² + 5. 42 : 1769 → 42² + 5 → 1764 + 5 = 1769 34 → 34² + 5 = 1156 + 5 = 1161
I. 2p2 + 25p – 13 = 0
II. 2q2 – 19q = 2q + 23
I). p2 = 81
II). q2 - 9q + 14 = 0
I. 12y2 + 11y – 15 = 0
II. 8x2 – 6x – 5 = 0
I. 2x2 – 5x - 12 = 0
II. y2 – 11y + 30 = 0
(i) 2x² – 9x + 10 = 0
(ii) 4y² – 12y + 9 = 0
I. 2x² - 12x + 16 = 0  Â
II. 4y² - 8y - 12 = 0  Â
I. y/16 = 4/yÂ
II. x3 = (2 ÷ 50) × (2500 ÷ 50) × 42 × (192 ÷ 12)
I. 2x2 - 9 x + 9 = 0
II. 2y2 - 7 y + 3 = 0
I. 9x2 + 45x + 26 = 0
II. 7y2 – 59y − 36 = 0
I. p2 – 15p + 56 = 0
II. q2 + 2q – 63 = 0
