Detailed Solution & Explanation

Let the shares of A,B,C,\displaystyle A, B, C, and D\displaystyle D be represented as 5x\displaystyle 5x, 2x\displaystyle 2x, 4x\displaystyle 4x, and 3x\displaystyle 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:
CD=1000C - D = 1000
Substitute the expressions for C\displaystyle C and D\displaystyle D in terms of x\displaystyle x:
4x3x=10004x - 3x = 1000
x=1000x = 1000
Now, we can find the share of B\displaystyle B, which is represented by 2x\displaystyle 2x:
B’s share=2x=2×1000=2,000B\text{'s share} = 2x = 2 \times 1000 = ₹2,000
This mathematically corresponds to **Option C**.
Note: The textbook answer key lists **Option A** (2,500\displaystyle ₹2,500) as the correct answer. However, the algebraic calculation clearly shows that B\displaystyle B's share is 2,000\displaystyle ₹2,000 (Option C). This is a known typographical discrepancy in the source material.
Hence, **Option C** is the correct answer.
