(a) 10

(b) 0

(c) -7

(d) -4

**Answer:**

Numbers ( Integers) 10, -7, 5, 3, -4 and 0 are marked on a number line the integer on the extreme left will be -7 .(c)

**Question 5. On the number line, the value of (-3) × 3 lies on the right hand side of**

(a) -10

(b) -6

(c) 0

(d) 9

**Answer:**

Value of (-3) × 3 = -9 lies on the right side of -10 as (-10) < (-9) (a)

**Question 6. The value of 5 ÷ (-1) does not lie between**

(a) 0 and-10

(b) 0 and 10

(c) -3 and -10

(d) -7 and 7

**Answer:**

5 ÷ (-1) = 5 – 1 = -5

-5 does not lie between 0 and 10 are positive integer.

0 and 10 (b)

**Question 7. The next number in the pattern -62, -37, -12, ……. is**

(a) 25

(b) 0

(c) 13

(d) -13

**Answer:**

-62 , -37, -12,…..

Next number is 0. (b)

**Question 8. Multiplication of integers satisfies the property of**

(a) closure

(b) commutativity

(c) associativity

(d) all of these

**Answer:**

Multiplication of integers satisfies the property of closure, commutative, associative i.e. all there properties. (d)

**Question 9. The number of integers between -20 and -10 are**

(a) 8

(b) 9

(c) 10

(d) 11

**Answer:**

The number of integers between -20 and -10 are 9

( -19, -18, -17, -16, -15, -14,-13, -12, -11, ) (b)

**Question 10. If the sum of two integers is -10 and one of them is 2, then the other is**

(a) 8

(b) -8

(b) 12

(d) -12

**Answer:**

Sum of two integers = -10

One integers = 2

Then Second integer will be = -10 – (2) = -12 (d)

**Question 11. The integer that must be subtracted from -5 to obtain -12 is**

(a) 7

(b) -7

(c) 17

(d) -17

**Answer:**

The integer will -12 if -5 is subtracted from that -5 (…..) = -12

12 – 5 = 7 (a)

**Question 12. Which of the following is not the additive inverse of a?**

(a) -(-a)

(b) -a

(c) a ÷ (-1)

(d) a × (-1)

**Answer:**

Additive inverse of a is not a i. e – (-a) (a)

**Question 13. 0 ÷ (-10) is equal to**

(a) 0

(b) -1

(c) -10

(d) none of these

**Answer:**

0 ÷ (-10) = 0 -10 = 0 (a)

**Question 14. (-33) × 102 + (-33) × (-2) is equal to**

(a) 3300

(b) -3300

(c) 3432

(d) -3432

**Answer:**

(-33) × 102 + (-33) × (-2) = (-33) (102-2) = -33 × 100 = -3300 (b)

**Question 15. 101 × (-1) + 0 ÷ (-1) is equal to**

(a) -101

(b) 101

(c) -102

(d) 102

**Answer:**

101 × (-1) + 0 ÷ (-1) = -101 + 0 = -101 (a)

**Question 16. If a and b are two integers, then which of the following may not be an integer?**

(a) a + b

(b) a – b

(c) a × b

(d) a ÷ b

**Answer:**

A and B are two integers, then

By closure proper a ÷ b is not an integer . (d)

**Question 17. For a non-zero integer a which is the following is not defined?**

(a) a ÷ 0

(b) 0 ÷ a

(c) a = 1

**Higher Order Thinking Skills (HOTS)**

**Question 1. Arrange the number -5 + 8, 3 x (-4). -15 ÷ 5, |-5 -7|, -7 -3 x (-2) and -7 -4 ****÷(-2) in descending order.**

**Answer:**

-5+8, 3×(-4). -15÷5, |-5-7|, -7-3×(-2) and -7-4÷(-2)

=> 3, -12-5, 12, -7-(+6), -7+2

=> 3, -17, 12, -1, -5

=> 12>3>-1>-5>-17.

That means….

|-5-7|> -5+8> -7-3 x (-2)> -7-4/(-2)> 3 x (-4)-15/5.

**Question 2. Write a pair of integers whose product is -12 and there lies seven integers between them.**

**Answer:**

Product of two integers = -12

The pairs can be possible

1 × 12 , 2 × 6 , 3 × 4

But has 7 integers between them the pair can be -2× 6 or -6 × 2

And seven integers between them will be

-1, 0, 1, 2, 3, 4, 5, or -5, -4, -3, -2, -1, 0, 1

**Question 3. A shopkeeper earns a profit of ₹ 2 by selling a pen and incurs a loss of 50 paise per pencil and loss of 15 paise per eraser while selling pencils and erasers of old stock. On a particular day, he earns a profit of ₹ 10. If he sold 10 pens and the number of pencils and erasers he sold are in the ratio 7 : 10, then find the number of pencils and eraser she sold on that day.**

**Answer:**

By selling a pen, gain is 2

And by selling a pencils , he loses 50 praise

And an eraser, he loses 15 praise

On one day, he gains = 10

On that day he sold 10 pens and pencils and erasers in the ratio of 7 :

10

On ten pens, his gain = 10 × 2 = 20

Loss on pencils and erasers = 20 -10 = 10 = 1000 praise

Ratio in pencil and erasers = 7 : 10

Let number of pencils = 7x, then eraser = 10x

7x × 50 + 10x × 15 = 1000

⟹ 350x + 150x = 1000

⟹ 500x = 1000

⟹ x = 2

Number of pencils = 7 × 2 = 14

And number of erasers = 10 × 2 = 20
