**Answers**

1. Ans.(e)

x = √8

y = √8

So, x=y

2. Ans.(b)

x = 18

y = 18, -18

So, x>=y

3. Ans.(a)

x = 2

y = -1

So, x>y

4. Ans.(a)

x = 17

y = 9

So, x>y

5. Ans.(c)

x = -7, -3

y = 7, 8

So, x<y

6. c

The series is

5^3 – 1 = 124

6^3 – 1 = 215

7^3 – 1 = 342

8^3 – 1 = 511

9^3 – 1 = 728

10^3 – 1 = 999

Reqd answer = 728.
