THE ANSWER IS OPTION B ✔ ✔

Answer 2

Concept:

We need to first recall the concept of division.

Division is the concept of dividing the dividend by divisor.

Given:

A pair of integer (a,b) such that a ÷ b = 2

To find:

A pair from the options which does not satisfy the given condition.

Solution:

In option (a)

 (a,b) = (-6,-3)

a ÷ b = (-6) ÷ (-3)

         = 2

so, option (a) satisfies the given condition.

In option (b)

 (a,b) = (-2,1)

a ÷ b = (-2) ÷ (1)

         = -2

so, option (b) does not satisfies the given condition.

In option (c)

 (a,b) = (-10,-5)

a ÷ b = (-10) ÷ (-5)

         = 2

so, option (c) satisfies the given condition.

In option (d)

 (a,b) = (8,4)

a ÷ b = (8) ÷ (4)

         = 2

so, option (d) satisfies the given condition.

Hence, the pair (-2,1) does not represent pair of integers (a,b) such that  

a ÷ b = 2.

option(b) is correct choice.
