Question 21

Question.  21

Kanta has p pencils in her box. She puts q more pencils in the box. The total number of pencils with her are

(A)

p + q

(B)

pq

(C)

p – q

(D)

p/q

Detailed Answer with Explanation:

Step 1: Kanta already has \(p\) pencils.

Step 2: She puts \(q\) more pencils into the box.

Step 3: To find the total, we add what she had and what she added.

\( ext{Total} = ext{existing pencils} + ext{added pencils} \)

\( ext{Total} = p + q \)

Therefore, the correct answer is A) \(p + q\).

Why the other options are wrong:

  • \(pq\): This means multiply, not add.
  • \(p - q\): This means subtract; she didn’t remove pencils.
  • \(p/q\): This means divide; no sharing or splitting happened.
