Question. 31
Number of pencils bought for Rs x at the rate of Rs 2 per pencil is _________.
Answer:
Number of pencils bought for Rs x at the rate of Rs 2 per pencil is x/2.
Detailed Answer with Explanation:
Step 1: We have total money = Rs \(x\).
Step 2: Price of 1 pencil = Rs \(2\).
Step 3: Number of pencils = (Total money) ÷ (Price of 1 pencil)
\(\text{Number of pencils} = \dfrac{\text{Total money}}{\text{Price of 1 pencil}}\)
\(= \dfrac{x}{2}\)
Quick check (example): If \(x=10\), then \(\dfrac{10}{2}=5\) pencils. So the formula works.
