Answer Key-
Q1. (4)
-32, - 16, - 8, - 4, - 2
Q2. (4)
Q3. (2)
15 × 1 + 5 = 20
20 × 2 + 5 = 45
45 × 3 + 5 = 140
140 × 4 + 5 = 565
565 × 5 + 5 = 2830
Q4. (4)
3 × 1 + 12 = 4
4 × 2 + 22 = 12
12 × 3 + 33 = 45
45 × 4 + 44 = 196
196 × 5 + 55 = 1005
Q5. (2)
12 × 12 × 1 =1728
14 × 14 × 14 = 2744
16 × 16 × 16 = 4096
18 × 18 × 18 = 5832
20 × 20 × 20 = 8000
And so on .....
? = 24 × 24 × 24 = 13824
Q6. (5)
x = +4 | - 4
y = 1 | -1
Q7. (5)
7y - 1 = 
7y = 14
y = 2
x +
= 2+ 
= 2+
x = 2
Q8. (2)
Required % = 
= 32.5%
= 32.5%
Q9. (3)
Let the width of the road is x m.
According to the question-
Area of lawn = {55 x 45 – (55 x + 45 x – x2)}
2091 = 2475 – 100x – x2
x2 – 100 x – 384 = 0 => (x – 4) (x – 96) = 0
x = 4 because x cannot be equal to 96.
Q10. (5)
Let the number of unsuccessful student = x
Then number of successful student = 4x
So, total number of student = 5x
According to Question-
{(5 x – 35) – (x + 9)} : (x +9) = 2 : 1
x = 31
so, total number of student = 5 x = 5 x 31 = 155
