1890 Find the missing number in the following number series:Solution
The series follows the pattern: 2 × 1 = 2 2 × 3 = 6 6 × 5 = 30 30 × 7 = 210 210 × 9 = 1890
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
I. x2 – 9x + 18 = 0
II. y2 – 5y + 6 = 0
I. 2x2 – 10x – 48 = 0
II. y2 – 16y – 297 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 143 = 0
Equation 2: y² - 26y + 165 = 0
Equation 1: x² - 90x + 2025 = 0
Equation 2: y² - 88y + 1936 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 27x² + 120x + 77 = 0
II. 56y² + 117y + 36 = 0
I. 96x² + 52x - 63 = 0
II. 77y² + 155y + 72 = 0
I. √(17x) + √51 = 0
II. √(4y) + 3 = 0
