Question
Select the option that is related to third
number-cluster in the same way first number-cluster is related to second number-cluster. 74: 33 :: 82: ?Solution
The logic followed here is the absolute difference between the square of the digits of the given number. Let 'AB' be first number then, number related to 'AB' is | A² - B²| In '74: 33' → 7² - 4² = 49 - 16 = 33 Similarly, in '82: ?' → 8² - 2² = 64 - 4 ? = 60 So, '74' is related to '33' in the same way '82' is related to '60'.
I). p2 - 26p + 165 = 0
II). q2 + 8q - 153 = 0
I. 2x² - 12x + 16 = 0  Â
II. 4y² - 8y - 12 = 0  Â
Equation 1: x² - 250x + 15625 = 0
Equation 2: y² - 240y + 14400 = 0
I. 88x² - 13 x – 56 = 0
II. 15 y² + 41 y + 28 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 17x² - 78x + 61 = 0
Equation 2: 19y² - 89y + 70 ...
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
Solve: 3x² − 7x − 6 = 0
I. x² - 33x + 270 = 0
II. y² - 41y + 414 = 0
I. 27x² + 120x + 77 = 0
II. 56y² + 117y + 36 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
