From a full tank, 60% of all water was poured, then 25% of the rest was poured. How much% of all water is left in the tank?

1. First, let’s find how much% of the water is left in the tank after 60% has been poured out of it:

100% – 60% = 40%;

2. Let’s find out how many percent were poured a second time:

40% / 100% * 25% = 10%.

3. Let’s find how many percent of all the water is left in the tank:

40% – 10% = 30%.
