Acontainer with a capacity of 3/5 litres was filled completely with water. 180ml of water from the container was used to water some plants.
what percentage of the container is filled with water now ?

1 liter=1000ml

3/5 of 1000ml=600ml

full=600ml
minus 180ml used to water to get
600ml-180ml=420ml

percent?
420/600=70/100=70%

70% full

It is going to be the third choice

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
