A bucket of 20 litres is 35%full.how many litres of water must be put into it so that it is 65% full?
presetly = 35% of 20 liters 35/100*20 = 7litres we need 65/100*20=13litres the litres we need to put in the bucket is 13litres - 7 litres=6litres

To find out how many liters of water must be put into the bucket to make it 65% full, we need to follow these steps:
Step 1: Calculate the amount of water already present in the bucket.
Since the bucket is currently 35% full, we multiply 35% by the total capacity of the bucket (20 liters) to find the amount of water already in the bucket.
35/100 × 20 = 7 liters
So, there are 7 liters of water already in the bucket.
Step 2: Calculate the total volume of water needed to make the bucket 65% full.
To find out how many liters of water are needed to make the bucket 65% full, we subtract the amount of water already in the bucket from the desired total capacity.
Desired capacity = 65% of 20 liters
= 65/100 × 20
= 13 liters
Volume of water needed = Desired capacity - Current volume
= 13 liters - 7 liters
= 6 liters
Therefore, 6 liters of water must be added to the bucket to make it 65% full.
