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.
