Answer
Solving,
⇒ -6x < -40
⇒ 6x > 40
⇒ x >
⇒ x >
⇒ x > .
Since, x ∈ W
∴ x = {7, 8, 9, ……}
∴ Assertion (A) is false.
We know that,
If each term of an in-equation be multiplied or divided by the same negative number, the sign of inequality reverses.
∴ Reason (R) is true.
Hence, Option 2 is the correct option.
