Question
Direction: Find the wrong number in given number
series. 1102, 1140, 1186, 1240, 1318, 1412.Solution
Here series follows the pattern- 1102+19*2 = 1140 1140+23*2 = 1186 1186+29*2 = 1244 1244+37*2 = 1318 1318+47*2 = 1412
For 3x² − 10x − 8 = 0, find (1/α + 1/β).
I. 88x² - 13 x – 56 = 0
II. 15 y² + 41 y + 28 = 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer Â
I. 7x² - 19x + 10 = 0...
I. 12y2 + 11y – 15 = 0
II. 8x2 – 6x – 5 = 0
I. x2 + 16x + 63 = 0
II. y2 + 2y - 15 = 0
The equation x2 – px – 60 = 0, has two roots ‘a’ and ‘b’ such that (a – b) = 17 and p > 0. If a series starts with ‘p’ such...
I. 2p² - 11p + 12 = 0
II. 2q² - 17q + 36 = 0
I. 84x² - 167x - 55 = 0
II. 247y² + 210y + 27 = 0
I. 6 y² + 11 y – 7= 0
II. 21 x² + 5 x – 6 = 0
I. x2 + x – 42 = 0
II. y2 + 6y – 27 = 0
