Correct Answer

✅ Option c — ₹2,000\displaystyle ₹2,000

All Options:

  • A₹2,500\displaystyle ₹2,500
  • B₹1,500\displaystyle ₹1,500
  • C₹2,000\displaystyle ₹2,000
  • D₹1,000\displaystyle ₹1,000

Detailed Solution & Explanation

Let the shares of $A, B, C,$ and D\displaystyle D be represented as $5x\displaystyle , $2x, $4x$, and $3x$ respectively, where x\displaystyle x is a common ratio constant.
According to the problem, C\displaystyle C gets ₹1000\displaystyle ₹1000 more than D\displaystyle D:
C−D=1000C - D = 1000
Substitute the expressions for C\displaystyle C and D\displaystyle D in terms of x\displaystyle x:
4x−3x=10004x - 3x = 1000
x=1000x = 1000
Now, we can find the share of B\displaystyle B, which is represented by $2x\displaystyle \text{&amp;̲#x27;s share} =…" style="color:#cc0000">\displaystyle :<br><span class="katex-display"><span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML" display="block"><semantics><mrow><mi>B</mi><mtext>’s share</mtext><mo>=</mo><mn>2</mn><mi>x</mi><mo>=</mo><mn>2</mn><mo>×</mo><mn>1000</mn><mo>=</mo><mtext>₹</mtext><mn>2</mn><mo separator="true">,</mo><mn>000</mn></mrow><annotation encoding="application/x-tex">B\displaystyle \text{&amp;#x27;s share} = 2x = 2 ×\displaystyle \times 1000 = ₹2,000</annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.6944em;"></span><span class="mord mathnormal" style="margin-right:0.05017em;">B</span><span class="mord text"><span class="mord">’s share</span></span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">=</span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.6444em;"></span><span class="mord">2</span><span class="mord mathnormal">x</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">=</span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.7278em;vertical-align:-0.0833em;"></span><span class="mord">2</span><span class="mspace" style="margin-right:0.2222em;"></span><span class="mbin">×</span><span class="mspace" style="margin-right:0.2222em;"></span></span><span class="base"><span class="strut" style="height:0.6444em;"></span><span class="mord">1000</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">=</span><span class="mspace" style="margin-right:0.2778em;"></span></span><span class="base"><span class="strut" style="height:0.8389em;vertical-align:-0.1944em;"></span><span class="mord">₹2</span><span class="mpunct">,</span><span class="mspace" style="margin-right:0.1667em;"></span><span class="mord">000</span></span></span></span></span><br>This mathematically corresponds to **Option C**.<br>Note: The textbook answer key lists **Option A** (
₹2,500$) as the correct answer. However, the algebraic calculation clearly shows that $B$'s share is $₹2,000$ (Option C). This is a known typographical discrepancy in the source material.
Hence, **Option C** is the correct answer.
