Question - 1

Lost - time accidents in both years = 0.07 * 0.14 = 0.0098. As per the instructions given in question, we have round it to 3rd decimal where 9 will become 10. So .......... it will be 0.010

Lost time accidents in both years = 0.010 * 100 = 1 %

Explanation : Here ....... the requirement is to have accident in both years. That means 14% out of previous 7% will be counted for this purpose.

Question - b
