Question: A watch set correctly at 10 am on sunday shows 20 min more than the correct time at 6 pm on that day. If the clock shows 10.30 pm on the same day, what is the correct time?
How I solved:
In 8 hours( 10 am to 6 pm ) its gaining 20 mins
Hence in 12.5 hrs( 10 am - 10.30 pm) it should gain = (20/8)* 12.5 = 31.25 mins.
but the actual answer is 10 pm i.e. 30 mins less and mine is coming more than 30 mins less(31.25 mins to be exact)
What I am missing?

A cylindrical overhead tank is filled up by two pumps - P1 and P2. P1 can fill the tank in 8 hours while P2 can fill the tank in 12 hours. There is a pipe P3 which can empty the tank in 8 hours. Both the pumps P1 and P2 are opened simultaneously. The supervisor of the tank, before going out on a work, sets a timer to open P3 when the tank is half filled so that it is exactly filled up by the time he is back. The timer went awry and as a result, P3 was opened when the tank was only 1/3rd full. If he returns as per his schedule, what percent of the tank would still be empty?
25% tank
12% tank
10% tank
None of the above
solution please
