 Discuss Question
Answer: Option B. -> +7
:
B
The integers that lie between -8 and +6 are-7, -6, -5, -4, -3, -2 , -1, 0, 1, 2, 3, 4.
Hence fromthe given options, we can see that +7 does not lie between -8 and +6.

  3.    Both the statements are false
  4.    Both the statements are true
 Discuss Question

Question 13. The temperature of different cities are as follows:
Delhi36CKolkata24CBangalore20CPatna2CShillong2CSrinagar0C
Which city is the coolest?
  1.    Srinagar 
  2.    Bangalore
  3.    Kolkata 
  4.    Shillong
 Discuss Question
Answer: Option D. -> Shillong
:
D
The city with the least temperature is the coolest city. Among the given numbers 36 > 24 > 20 > 2 > 0 > -2 .
Hence, the city with least temperature isShillong i.e.,2C.
Question 14. Arrange in ascending order:
-1, -11 , 111 , -111 , 11 , 0 , 1
  1.    -1 , -11 , 111 , -111 , 11 , 0 , 1   
  2.    -111 , -11 , -1 , 0 , 1 , 11 , 111   
  3.    -1 , 11 , 111 , -111 , -11 , 0 , 1 
  4.    1, -11 , -111 , 111 , 11 , 0 , -1   
 Discuss Question
Answer: Option B. -> -111 , -11 , -1 , 0 , 1 , 11 , 111   
:
B
When considering negative numbers, the bigger the number, smaller is its value.
So, -111 is less than -11.
Similarly, -11 is less than -1.
Hence, among the given numbers, -111 is the smallest and 111 is the biggest number.
Ascending order of numbers is the arranging of numbers from smallest to largest.
So, the given numbers in ascending order is -111, -11, -1, 0, 1, 11, 111.
Question 15. Which of the following integers are less than -9? 
  1.    0, -1 ,-11 ,9 ,-9 ,99 ,-99 ,999 ,-999  
  2.    -8, -7, -6, -5, -4, -11, -12, -13, -14 
  3.    100, 1010,11, 1, 12, 122, 1222, 121212, 3
  4.    -11, -12, -151, -121, -11111, -12121212, -1345, -1111123
 Discuss Question
Answer: Option D. -> -11, -12, -151, -121, -11111, -12121212, -1345, -1111123
:
D
-10,-11,-12,-13,-14,,-15,-16,-17,-18,-19,-20.......and so on are less than -9.
Hence, from the given options

-11, -12, -151, -121, -11111, -12121212, -1345, -1111123 are all less than -9.
Question 16. -5 is ___ +5. Fill the gap with appropriate symbol (mention whether greater than or lesser than or equal to)
 Discuss Question

:
All positive integers are greater than negative integers. So -5 is lesser than +5
Question 17. The temperature 26C above 0C  and 13C  below 0C can be represented as-
  1.    -26∘C and +13∘C
  2.    +26∘C and -13∘C     
  3.    -26∘C and -13∘C
  4.    +26∘C and +13∘C
 Discuss Question
Answer: Option B. -> +26∘C and -13∘C     
:
B
The temperature26Cabove 0Ccan be represented as+26Cand the temperature13Cbelow 0Ccan be represented as -13C.

Question 20. A building has 20 stairs above ground level and 20 stairs below ground level. If you are standing at the 16th step below ground level, then how will you represent it mathematically?
  1.    You are at +16th step.
  2.    You are at -16th step.
  3.    You are at -4th step.
  4.    You are at 4th step.
 Discuss Question
Answer: Option B. -> You are at -16th step.
:
B
When we compare the stairs to a vertical number line, theground level can be taken as zero,the stairs above the ground level areconsidered as positive integersand the stairs below the ground level are considered as negative inetgers. So, if you are standing at the 16th step below ground level then,wecan say that you are at -16th step.
