(a) A is cooler than B
(b) B is cooler than A
(c) There is a difference of 2°C in the temperature
(d) The temperature at A is 4°C higher than that at B
Solution:
(a) We know that, if the temperature decreases, the cooling increases.
Given, minimum temperature on a particular at A = -4°C and minimum temperature on a particular at B = -1°C We know that, -4 °C < -1° C So, A is cooler than 6.
Hence, option (a) is true.

Question 15:
When a negative integer is subtracted from another negative integer, the sign of the result
(a) is always negative
(b) is always positive
(c) is never negative
(d) depends on the numerical value of the integers
Solution:
(d) Suppose we take two negative integers -2 and -3.
We subtract (-3) from (-2) and give a minus sign to get the result.
i.e -2 -(-3) = -2 + 3 = 1
Again, we subtract (-2) from -3 and give a plus sign to get the result.
i.e -3 – (-2) = – 3 + 2 = -1
So, the sign of the result depends on the numerical value of the integers.

Question 16:
The statement “When an integer is added to itself, the sum is greater than the integer” is
(a) always true
(b) never true
(c) true only when the integer is positive
(d) true for non-negative integers
Solution:
(c) Suppose we take two integers one positive (+1) and other negative -1.
On adding 1 to itself, we get
1 + 1=2
Here, the sum is greater than the integer (+1).
Again, adding -1 to itself, we get
-1+ (-1) =—1 — 1 = — 2 Here, the sum is less than the integer -1.
Hence, the given statement is true only when the integer is positive.

Question 17:
Which of the following shows the maximum rise in temperature?
(a) 0°C to 10°C (b) -4° C to 8° C (c)-15°C to-8° C (d)-7°C to O°C
Solution:
(b) We know that, the maximum rise in the temperature is equal to the maximum value of difference of two temperatures.
(a) Difference of 0°C to 10°C = 10°C – 0°C= + 10°C
(b) Difference of -4°C to 8°C =8°C -(-4°C) = 8°C + 4°C = + 12°C [maximum]
(c) Difference of-15°C to-8°C = -8°C-(-15°C)=-8°C+15°C = +7°C
(d) Difference of -7°C to 0°C = 0°C -(-7°C)= 0°C + 7°C = +7°C Hence, the option (b) shows the maximum rise in temperature.

Question 71:
Using number line, how do you compare
(a) two negative integers?
(b) two positive integers?
(c) one positive and one negative integers?
Solution:
We know that, on the number line, points to the right of zero are positive integers and points to the left of zero are negative integers.
Also, if move from left to the right on the number line, then number increases and if we move from right to the left on the number line, then number decreases.
(a) If we compare two negative integers on the number line, then the number which is on the right of the other number, will be greater.
e.g. Here, we see that – 2 is on the right of – 3, so -2 is greater and – 3 is smaller.
(b) If we compare two positive integers on the number line, then the number which is on the right of the other number, will be greater.
e.g. , Here, we see that 3 is on the right of 1, so 3 is greater and 1 is smaller.
(c) If we compare one positive and one negative integers on the number line, then a positive integer is always greater than the negative integer.
e.g. Here, we see that 2 is on the right of – 1, so 2 is greater and -1 is smaller.

Question 72:
Observe the following:
l+2-3+4+5-6-7+8-9=-5 Change on sign as V sign to get the sum 9.
Solution:
LHS=1+2-3+4+5-6-7+8-9 = (3 – 3) + (9 – 9) – 6 – 7 + 8 =0+0-6-7+8=2-7
Now, we have to get the sum 9, so replace the sign of (-) into (+) before 7.
LHS =2 + 7 = 9

Question 73:

0>-1>-2>-3>-4>-6

Question 75:
Write two integers whose sum is 6 and difference is also 6.
Solution:
We know that, on adding zero to an integers, the sum is the integer itself, e.g. 6+0 = 6
Also, if we subtract zero from an integer, the difference is the integer itself, e.g. 6-0=6
Hence, the required two integers are 0 and 6.

Question 76:
Write five integers which are less than – 100 but greater than – 150.

All the integers lying between -100 and -150 are less than -100 and greater than -150. So, – 101, -102, – 103, – 104 and – 105 are such five integers.
Note There can be many answers of this question.

Question 77:
Write four pairs of integers which are at the same distance from 2 on the number line.
Solution:
As the pairs of integers should be same distance from 2 on the number line. Therefore, the required pairs are
(1,3) -> both are at a distance of 1 unit.
(0, 4) -> both are at a distance of 2 units.
(-1, 5) -> both are at a distance of 3 units.
(- 2, 6) ->both are at a distance of 4 units.
Note There may be many pairs.

Question 78:
The sum of two integers is 30. If one of the integer is – 42, then find the other.
Solution:
Given, sum of two integers = 30
and one integer =-42
The other integer = Sum of two integers – One integer = 30 – (- 42) = 30+ 42 = 72
Hence, the other integer is 72.

Question 79:
Sum of two integers is -80. If one of the integer is – 90, then find the other.
Solution:
Given, sum of two integers = – 80
and one integer = – 90
The other integer = Sum of two integers – One integer = (- 80) – (- 90) = – 80 + 90 = 10
Hence, the other integer is 10.

Question 80:
If we are at 8 on the number line, then in which direction should we move to reach the integer
(a) -5? (b) 11? (c) 0?
Solution:
Firstly, we draw a number line and mark some points at equal distance on it. (a) Clearly, if we move towards – 5 from 8, then we are moving in left direction.
(b) Clearly, if we move towards 11 from 8, then we are moving in right direction.
(c) Clearly, if we move towards 0 from 8, then we are moving in left direction.

Question 81:
Using the number line, write the integer which is
(a) 4 more than – 5.
(b) 3 less than 2.
(c) 2 less than – 2.
Solution:
(a) Firstly, we draw a number line.
Now, to get the integer 4 more than -5, we start from -5 and move 4 steps to the right of -5 and reach at -1.
Flence, 4 more than -5 is -1. (b) Firstly, we draw a number line.
Now, to get the integer 3 less than 2, we start from 2 and move 3 steps to the left of 2 and reach at -1. Flence, 3 less than 2 is -1.
(c) Firstly, we draw a number line.
Now, to get integer 2 less than -2, we start from -2 and move 2 steps to the left of -2 and reach at -4. Flence, 2 less than -2 is -4.

Question 82:
Find the value of 49 – (- 40) – (- 3) + 69.
Solution:
We have, 49 – (- 40) – (- 3) + 69= 49 + 40 + 3 + 69
= 161

Question 83:
Subtract -5308 from the sum [(- 2100) + (- 2001)].
Solution:
Firstly, we find the sum
[(-2100) + (- 2001)] = [- 2100 – 2001]
= -4101
Now, subtract – 5308 from – 4101.
– 4101 – (- 5308) =-4101+ 5308 = 1207
