Answer Key-

1-Sol-(4)

-32, - 16, - 8, - 4, - 2

2-Sol-(4)


3-Sol-(2)

15 × 1 + 5 = 20

20 × 2 + 5 = 45

45 × 3 + 5 = 140

140 × 4 + 5 = 565

565 × 5 + 5 = 2830

4-Sol-(4)

3 × 1 + 1 = 4

4 × 2 + 2 = 12

12 × 3 + 32 = 45

45 × 4 + 42 = 196

196 × 5 + 52 = 1005

5-Sol-(2)

12 × 12 × 12 =1728

14 × 14 × 14 = 2744

16 × 16 × 16 = 4096

18 × 18 × 18 = 5832

20 × 20 × 20 = 8000

And so on .....

? = 24 × 24 × 24 = 13824

6-Sol-(5)

x = +4 | - 4

y = 1 | -1

7-Sol-(5)

7y - 1 =

7y = 14

y = 2

x + = 2+

x = 2

8-Sol-(2)

Required % = = 32.5%

9-Sol-(3)

Let the width of the road is x m.

According to the question-

Area of lawn = {55 x 45 – (55 x + 45 x – x)}

2091 = 2475 – 100x – x2

x– 100 x – 384 = 0 => (x – 4) (x – 96) = 0

x = 4 because x cannot be equal to 96.

10-Sol-(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
