Hello and welcome to ExamPundit. Here is a set of Quantitative Aptitude Quiz for Bank and Insurance Exams 2015. These are based on Quadratic Equations and Number Series.
Directions (Q. 15):
In each of these questions a number series is given. What value will come in
place of the question mark (?) in
the following series?
1. 0.5 ? 1.5 4.5 13
38.75
(a) 0.5
(b) 0.75
(c) 1
(d) 1.5
(e) None of these
Solutions (.5 + .5) × .5 = .5 (0.5 + 1) × 1 = 1.5 (1.5 + 1.5) × 1.5 = 4.5 (4.5 + 2) × 2 = 13
(13 + 2.5 ) × 2.5 = 387.5


2. 13 18 22 25 27 28
?
(a) 30
(b) 28
(c) 32
(d) 33
(e) None of these
3. 2 10 30 68 130 222
?
(a) 280
(b) 290
(c) 320
(d) 350
(e) None of these
Solutions 1 + 13 = 2 2 + 2^{3} = 10 3 + 3^{3} = 30 4 + 4^{3} = 68 5 + 5^{3} = 130 6 + 6^{3} = 222
7 + 7^{3} = 350


4. 11 24 16 38 27 64
?
(a) 34
(b) 38
(c) 44
(d) 36
(e) None of these
Solutions 11 × 2 + 2 = 24 24 ÷ 2 + 4 = 16 16 × 2+ 6 = 38 38 × 2 + 8 = 27 27 × 2 + 10 = 64
64 ÷ 2 + 12 = 44


5. 821 460 749 580
701 652 ?
(a) 668
(b) 677
(c) 766
(d) 686
(e) None of these
Solutions  821 – 192 = 460 460 + 17^{2} = 749 749 – 13^{2} = 580 580 + 11^{2} = 701 701 – 7^{2} = 652 652 + 5^{2} = 677 

Direction (Q. 610):
In the following questions, there are two equations (I) and (II) solve the
equations and answer according to
following codes:
(a) If x < y
(b) If x > y
(c) If x = y
(d) If x ≥ y
(e) If x ≤ y
6. I. 2x^{2} – 13x + 21 = 0
II. 2 y^{2} – 7y + 3 = 0
7. I. x^{2} – 12x + 35 = 0
II. 6y^{2} + 11y +3 = 0
8. I. 2x^{2} – 17 x +21 = 0
II. y^{2} – 15y + 56 = 0
9. I. x^{2} +2x – 8 = 0
II. 2y^{2} – 15y + 28 = 0
10. I. x = √^{1}/_{9}
II. 9y^{2} – 6y +1 = 0
