Dear Aspirants,
We have introduced "the 12 days study plan to crack IBPS SO Exam 2017". This plan is specifically dedicated to Quantitative Aptitude & English Language and cover all types of questions asked in Bank SO exams. This will help you to prepare in a more efficient and systematic way. So, follow this post to keep updated with the plan.
Directions (1 – 10) : In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer.
(a) if x > y
(b) if x ≥ y
(c) if x < y
(d) if x ≤ y
(e) if x = y or no relation can be established between ‘x’ and y.
1. I. 4x + 7y = 42
II. 3x – 11y = – l
2. I. 9x^2 – 29x + 22 = 0
II. y^2 – 7y + 12 = 0
3. I. 3x^2 – 4x – 32 = 0
II. 2y^2 – 17y + 36 = 0
4. I. 3x^2 – 19x – 14 = 0
II. 2y^2 + 5y + 3 = 0
5. I. x^2 + 14x + 49 = 0
II.y^2 + 9y = 0
6. I. 30x^2 + 11x + 1 = 0
II. 42y^2 + 13y + 1 = 0
7. I. x^2 – x – √2x + √2= 0
II. y^2 – 3y + 2 = 0
8. I. x^2 – 2x – √5x + 2√5 = 0
II. y^2 – √3y – √2y + √6 = 0
9. I. 9x^2 + 3x – 2 = 0
II. 8y^2 + 6y + 1 = 0
10. I. 3x² + 11x + 6 = 0
II. 3y² + 10y + 8 = 0
ANSWERS :
1. a
x = 7 ; y = 2
2. c
x = 2, 11/9
y = 3, 4
3. d
x = 4, -8/3
y = 4, 9/2
4. a
x = 7, -2/3
y = -3/2, -1
5. e
x = -7
y = 0, -9
6. d
x = -0.16, -0.19
y = -0.14, -0.16
7. e
x = 1, 1.414
y = 1, 2
8. a
x = 2, 2.23
y = 1.414, 1.732
9. e
x = 0.33, -0.66
y = -0.25, -0.5
10. e
x = -0.66, -3
y = -1.33, -2
