ist calculate live storage = total capacity - dead storage = 25 - 5 = 20million metercubic
then number of year = live storage capacity / sediment deposition in each year = 20 / 0.1 = 200 year
therefore the correct answer is 200 year

After filled up the dead storage the usefulness of the reservoir will start reducing
The storage will be filled up in
5/0.10 = 50 years
