Explanation:

To solve the problem, let's break it down:

- Let the votes for C be denoted by x.

- B receives 5% more votes than C: \( B = x + 0.05x = 1.05x \).

- A receives 50% more votes than B: \( A = 1.5 \times 1.05x = 1.575x \).

- A beats C by 18,000 votes: \( 1.575x - x = 18000 \).

- Solving this equation: \( 0.575x = 18000 \). Therefore, \( x = \frac{18000}{0.575} = 31304.35 \).

- Calculate total votes: \( A + B + C = 1.575x + 1.05x + x = 3.625x = 113501.03 \).

- Since 90% of voters voted: \( 0.9 \times \text{Voters} = 113501.03 \).

- Thus, total voters = \( \frac{113501.03}{0.9} = 126112.25 \).

1. Option 1: 1,00,000

2. Option 2: 81,000

3. Option 3: 90,000

4. Option 4: 1,10,000

These calculations show none of the options match the calculation exactly. However, approximating, the closest option is 1,10,000.

Correct Answer: Option 4: 1,10,000
