Assertion and Reason Questions

In the following questions (9-10), a statement of Assertion (A) is followed by a statement of Reason (R). Choose the correct option as:
(a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
(c) Assertion is true, and the reason is false.
(d) Assertion is false, and the reason is true.

Question 1.
Assertion (A): In the equation 6(p+3)=18 dividing both sides by 6 gives p+3=3.
Reason (R): When a variable term is multiplied by a constant, we can divide both sides by that constant to isolate the variable.
Solution:
(a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.

Question 2.
Assertion (A): The solution of 8-4 x=2(x-3)-(x-5) is x=3.
Reason (R): When we move a variable term from one side of an equation to the other, its sign changes.
Solution:
(d) Assertion is false, and the reason is true.

Solution:
equality

(d) The equation 2 x-3=7 can be written as x=…………
Solution:
5

(e) If \(\frac{x}{2}=9\), then x= ………….
Solution:
18

Match the following:


Solution:

Column A		Column B
(a)	-(n+ 1) = 2(n – 5)	(iii)	n = 3
(b)	4n = 12 + n	(i)	n = 0
(c)	6 (n + 1) = 6	(ii)	n = 3
(d)	3(8 – 2n) = -6	(v)	n = 5
(e)	3(n – 3) = -12	(iv)	n = -1
