Explanation:

- Let's define the salaries:

- A's salary = A

- B's salary = B

- C's salary = C

- We know:

- 2A = 5B (Two times A's salary is five times B's salary)

- 4B = 2C (Four times B's salary is twice C's salary)

- Given:

- C's salary = Rs1,600

- From 4B = 2C:

- Substitute C = Rs1,600

- 4B = 2 × 1,600 = 3,200

- B = 3,200 / 4 = Rs800

- From 2A = 5B:

- Substitute B = Rs800

- 2A = 5 × 800 = 4,000

- A = 4,000 / 2 = Rs2,000

Correct Answer: Option 1 - Rs2,000
