The formula to calculate handicap from index is:
\[ \text{H} = \frac{\text{I} \times \text{SR}}{113} \]
Where:
A handicap is defined as the number of strokes that a golfer receives on any particular course. It allows players of different skill levels to compete on an equal footing by adjusting their scores based on the difficulty of the course.
Let's assume the following values:
Using the formula:
\[ \text{H} = \frac{10 \times 120}{113} = \frac{1200}{113} = 10.62 \]
The handicap is 10.62.
