Olympiad Test: Integers - Class 6 MCQ

 The set of integers comprises negative numbers and whole numbers.

• Negative integers are numbers less than zero.
• The closer a negative number is to zero, the greater it is.
• -1 is closer to zero than -9 or -100.
• "Does not exist" is incorrect because negative integers are well-defined.
• Thus, -1 is the greatest negative integer.

Zero has no sign (+ or -). Si it is neither positive nor negative.

Excluding -11 and 11, the negative integers between them are -10,-9,-8,......-1.

The only integer which does not have a opposite is 0.  It is niether a positive or a negative number. 

1 is the smallest positive integer.

Negative numbers are located on the left side of 0 on the number line.

The opposite of rise in temperature by 5^o C is - 5^o C. 

The correct option is Option B.

North is (Positive) & South is (Negative)

Hence Option B is the Correct answer i.e -3 km

5 is an integer which is greater than -1 and less than 7.

Given:

Expression: 5 ÷ (-1)

Concept used:

Division of a positive number by a negative number results in a negative quotient.

Calculation:

5 ÷ (-1) = -5

Now let's check which range the value -5 lies in:

-10 < -5 < 0

∴ The value of 5 ÷ (-1) does not lie between 0 and 10.

The opposite of profit of Rs. 250 is loss of Rs. 250. 

(i) 36 + 14 = 50 

(ii) 38 + (-12) = 26 

(iii) (-18) + (30) = 12 

(iv) (-7) + (- 9) = - 16

• To find the sum of -10, -5, and 12, start by adding the negative numbers first:
• -10 + (-5) = -15
• Now, add 12 to -15:
• -15 + 12 = -3
• So, the final sum is -3.
• This matches option 4, which is the correct answer.

As the figure shows current temperature at - 12^oC. The temperature drops by 2^oC. 

The current temperature is -12 - 2 = - 14^oC.

(-4^∘C) + (4^∘C) + (-3^∘C) + (6^∘C) =3^∘C

The integers between - 3 and 3 are -2, -1, 0, 1 and 2.  

-6 lies between the integers -7 and -5.
