Question
Eight boys B1, B2, B3, B4, B5, B6, B7 and B8 are sitting
in a row facing towards the north (not necessarily in the same order). B6 is fifth to the right of B1. B4 is fifth to the right of B5. B5 is to the immediate right of B1. B8 is third to the left of B4. B2 is third to the right of B7. B7 is an immediate neighbour of B1. Who is sitting on the immediate right of B2?ÂSolution
The correct answer is A
I. x2 - 5x - 14 = 0
II. y2 - 16y + 64 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 27x² - 114x + 99 = 0
Equation 2: 18y² - 70y + 68 = 0
I. 56x² - 99x + 40 = 0
II. 8y² - 30y + 25 = 0
I). p2 - 26p + 165 = 0
II). q2 + 8q - 153 = 0
I. x2 + 91 = 20x
II. 10y2 - 29y + 21 = 0
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
I. 8x – 3y = 85
II. 4x – 5y = 67
I. 6x2 - 41x+13=0
II. 2y2 - 19y+42=0
