Given:

Rs. 2,000 is divided between A and B such that half of A's part and one-third of B's part are equal.

Formula used:

Let A's part be ₹x and B's part be ₹(2000 - x).

According to the problem,

\(\frac{x}{2} = \frac{2000 - x}{3}\)

Calculation:

\(\frac{x}{2} = \frac{2000 - x}{3}\)

⇒ 3x = 2(2000 - x)

⇒ 3x = 4000 - 2x

⇒ 3x + 2x = 4000

⇒ 5x = 4000

⇒ x = 800

B's part = 2000 - 800 = 1200

∴ The correct answer is option 1.
