To calculate the amount of compensation payable under the Employees' Compensation Act, 1923, we need to use the formula:
\[ \text{Compensation} = \text{Factor} \times \text{Monthly Wage} \times 50\% \]Given:
Substitute these values into the formula:
\[ \text{Compensation} = 159.80 \times 12000 \times 0.50 \]\[ = 159.80 \times 6000 \]\[= 958800 \]Therefore, the compensation amount payable is ₹9,58,800, which matches with the given correct answer option.
This approach conforms with the Employees' Compensation Act, which uses age-based factors to determine compensation in the event of a fatal accident at the workplace.
