Answer 1

100 percent is 5/5th so

75 percent is 4/5th full so take out 25 percent from 75 percent that is

50 percent means we are taking out 1/5th then the answer is

'50' percent .

I hope this answer will help you.

Answer 2

Answer:

20%

Step-by-step explanation:

Let's suppose bottle x liter is fully filled

Given, 4/5th is full

Therefore,  the amount full now is $\frac{4}{5}$x

Since the water evaporated is 25%

So, the equation is 25% of $\frac{4}{5}$x

=> 25 % of $\frac{4}{5}$x

=> $\frac{25}{100}$ × $\frac{4}{5}$x

=> $\frac{1}{4}$×$\frac{4}{5}$x

=> $\frac{x}{5}$

Hence, The water left is 1/5th of x liter i.e 20%
