**B**

$1/0.001$.

**C**

$0.001$.

**D**

$0.001^2$.

**Soln.**

**Ans: a**

We know that if a number is less than 1, then it becomes smaller and smaller as it is raised to higher and higher positive powers. Now, $1/0.001$ is same as $0.001^{-1}$. The three powers of 0.001 given to us are -1, 1, 2 and 3. Out of these 3 is the most positive, so, $0.001^3$ is the smallest.

### Question 2

What is y in $9.073 + 0.8 + y = 0.02$?

### Question 3

Which is the smallest?

**A**

$0.077^3$.

**B**

**C**

$0.077$.

**D**

$0.077^2$.

**Soln.**

**Ans: a**

We know that if a number is less than 1, then it becomes smaller and smaller as it is raised to higher and higher positive powers. Now, $1/0.077$ is same as $0.077^{-1}$. The three powers of 0.077 given to us are -1, 1, 2 and 3. Out of these 3 is the most positive, so, $0.077^3$ is the smallest.

### Question 4
