Explanation:

To solve this problem, we need to determine how many runs the batswoman scored in singles based on the given proportion of scoring shots. Here is a breakdown:

- The total runs the batswoman scored is 96 (since she missed the century by four runs).

- The ratio of scoring shots is 1 (sixes) : 3 (fours) : 2 (threes) : 7 (twos) : 10 (singles).

- Let's denote the common multiple of these proportions as 'x'.

- Sixes contribute 6 * 1x = 6x runs.

- Fours contribute 4 * 3x = 12x runs.

- Threes contribute 3 * 2x = 6x runs.

- Twos contribute 2 * 7x = 14x runs.

- Singles contribute 1 * 10x = 10x runs.

- Adding these contributions, we get the equation:

\(6x + 12x + 6x + 14x + 10x = 96\)

\(48x = 96\)

\(x = 2\)

- The runs scored in singles: 10x = 20 runs.

Therefore, the number of runs scored in singles is 20.

Correct Answer: Option 1 - 20
