(a) Both Assertion (A) and reason (R) are true and Reason (R) is a correct explanation of
Assertion (A).
(b) Both Assertion (A) and reason (R) are true and Reason (R) is not a correct explanation
of Assertion (A).
(c) Assertion (A) is true and Reason (R) is false.
(d) Assertion (A) is false and Reason (R) is true.

The correct answer is: (a) / (b) / (c) / (d)
Sol:
(a) Both Assertion (A) and reason (R) are true and Reason (R) is a correct explanation of
Assertion (A).

Clearly, reason (R) is true.
Using the relation in reason (R), we have:
2 mean = (3 × median) – mode = (3 × 150) – 154 = 450 – 154 = 296
⇒ Mean = 148, which is true.
∴ This assertion (A) and reason (R) are both true and reason (R) is the correct explanation
of assertion (A).
