Dear Students,
Numerical Ability or Quantitative Aptitude Section has given heebie-jeebies to the aspirants when they appear for a banking examination. As the level of every other section is only getting complex and convoluted, there is no doubt that this section, too, makes your blood run cold. The questions asked in this section are calculative and very time-consuming. But once dealt with proper strategy, speed, and accuracy, this section can get you the maximum marks in the examination. Following is the Quantitative Aptitude quiz to help you practice with the best of latest pattern questions.

9.6
12
30
Solution:
Pattern is
150 × 2 = 300
300 ÷ 5 = 60
60 × 2 = 120
120 ÷ 5 = 24
24 × 2 = 48
48 ÷ 5 = 9.6
Q8. 106, 184, 267, 357, 456, ?
486

Solution:
Q9. 142, 119, 100, 83, 70, ?
69
49
42
59
53
Solution:
Pattern is
142 – 23 = 119
119 – 19 = 100
100 – 17 = 83
83 – 13 = 70
70 – 11 = 59
Q10. 120, 60, 90, 225, ?
782.5
787.5
752.5
875
855.5
Solution:
Pattern is
×0.5, ×1.5, ×2.5, ×3.5, ×4.5 ….
∴ 225 × 3.5 = 787.5
Directions (11-15): Solve the given quadratic equations and mark the correct option based on your answer—
Q11. (i) x² – x – 132 = 0
(ii) y² – 22y + 112 = 0
x > y
x ≥ y
x < y
x ≤ y
x = y or no relation can be established between x and y.
Solution:
X² – 12x + 11x – 132 = 0
x(x – 12) + 11 (x – 12) = 0
(x + 11) (x – 12) = 0
x = –11, 12
y² – 14y – 8y + 112 = 0
y(y – 14) – 8(y – 14) = 0
(y – 8) (y – 14) = 0
y = 8, 14
No relation can be established between x & y.
Q12. (i) x² – 8x + 15 = 0
(ii) y² – 2y – 3 = 0
x > y
x ≥ y
x < y
x ≤ y
x = y or no relation can be established between x and y.
Solution:
x² – 3x – 5x + 15 = 0
(x – 3) (x – 5) = 0
x = 3, 5 y² – 3y + y – 3 = 0
y(y – 3) + 1 (y – 3) = 0
(y + 1) (y – 3) =0
y = –1, 3
x ≥ y
Q13. (i) x² + 5√3 x+18=0
(ii) y²-√3 y-18=0
x > y
x ≥ y
x < y
x ≤ y
x = y or no relation can be established between x and y.
Solution:
x²+2√3 x+3√3 x+18=0
x(x+2√3)+3√3 (x+2√3)=0
(x+3√3)(x+2√3)=0
x=-3√3,-2√3
y²+2√(3) y-3√(3 ) y-18=0
(y+2√3)(y-3√3)=0
y= -2√(3,) 3√3
y ≥ x
Q14. (i) 2x² – x – 3 = 0
(ii) 4y² – 24y + 35 = 0
x > y
x ≥ y
x < y
x ≤ y
x = y or no relation can be established between x and y.
Solution:
2x² – x – 3 = 0
(x + 1) (2x – 3) = 0
x= -1, 3/2 4y² – 24y + 35 = 0
4y² – 14y – 10y + 35 = 0
y=5/2, 7/2
y > x
Q15. (i) 2x² – 7x + 6 = 0
(ii) 2y² – y– 1= 0
x > y
x ≥ y
x < y
x ≤ y
x = y or no relation can be established between x and y.
Solution:
2x²– 3x – 4x + 6 = 0
x(2x – 3) – 2 (2x – 3) = 0
(x – 2) (2x – 3) = 0
x=2, 3/2
2y² – 2y + y – 1 = 0
2y(y – 1) + 1 (y – 1) = 0
(2y + 1) (y – 1) = 0
y = -1/2 , 1
x > y
