### Percentage Problems

Percentage Calculator to solve calculations involving Percentages, here X and Y are Numbers and P is percentage.

**What is P percent of X?**

The above problem can be written in equation format :

Y = P% * X

**What is 25% of 60?**

- Y = 25% of 60
- Y = (25/100) *60
- Y = 15

Therefore 25% of 60 is 15

**Y is what percent of X?**

The above problem can be written in equation format :

Y = P% * X

P% = Y / X

**15 is what percentage (5) of 60?**

- P% = 15/60
- P% = 0.25
- P = 0.25 * 100
- P = 25

Therefore 15 is 25% of 60

**Y is P% of What?**

The above problem can be written in equation format :

Y = P% * X

X = Y / P%

**15 is 25% of what?**

- X = 15 / 25%
- X = 15 / (25/100)
- X = 15/ 0.25
- X = 15 * 100/25
- X = 15 * 4
- X = 60

Therefore 15 is 25% of 60

**What percent (% ) of X is Y?**

The above problem can be written in equation format :

P% * X = Y

P% = Y / X

**What percentage of 60 is 15?**

- P% = 15/60
- P% = 0.25
- P%= 0.25
- P = 0.25 * 100
- P = 25

Therefore 25% of 60 is 15.

**P% of What is Y?**

The above problem can be written in equation format :

P% * X = Y

X = Y / P%

**25% of what number is 15?**

- X = 15/25%
- X = 15/0.25
- X = 15 * 100/25
- X = 15 * 4
- X = 60

Therefore 25% of 60 is 15.

**P% of X is What?**

The above problem can be written in equation format :

P% * X = Y

Y = P% * X

**25% of 60 is what?**

- Y = 25% * 60
- Y = (25/100) * 60
- Y = 0.25 * 60
- Y = 15

Therefore 25% of 60 is 15.

**Y out of What is P%?**

The above problem can be written in equation format :

Y/X = P%

X = Y/P%

**15 of what is 25%?**

- X = 15/25%
- X = 15/0.25
- X = 15 * 100/25
- X = 15 * 4
- X = 60

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

**What out of X is P%?**

The above problem can be written in equation format :

Y/X =P%

Y= P% * X

**What out 60 is 25%? or What of 60 is 25%?**

- Y = 25% * 60
- Y = 25/100 * 60
- Y = 0.25 * 60
- Y = 15

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

**Y out of X is What %?**

The above problem can be written in equation format :

Y/X = P%

P% = Y/X

**15 out 60 is what percent? or 15 of 60 is what percent?**

- P% = 15/60
- P% = 0.25
- P = 0.25 * 100
- P = 25

Therefore 15 of 60 is 25%. (15 out of 60 is 25%)

**X plus P% is What?**

The way to ask the same question is What is the P percentage increase from X?

The above problem can be written in equation format :

X + X * P% = Y

X (1 + P%) = Y

Y = X * (1 + P%)

**20 plus 30% is what? or what is 30% increase from 20?**

- Y = 20 * (1 + 30%)
- Y = 20 * (1 + 0.30)
- Y = 20 * 1.30
- Y = 26

There fore 30% increase from 20 is 26 or 20 plus 25% (6 is 25% of 20) is 26

**X plus What % is Y?**

The way to ask the same question is What is the percentage increase from X to Y?

The above problem can be written in equation format :

X + X * P% = Y

X*P% = Y – X

P% = (Y – X)/X

P% = Y/X – X/X

P% = Y/X -1

**20 plus what percentage is 26? or what is percentage increase from 20 to 26?**

- P% = 26/20 -1
- P% = 1.3 – 1
- P% = 0.30
- P = 30%

There fore 30% increase from 20 is 26 or 20 plus 25% (6 is 25% of 20) is 26

Therefore 20 plus 30% is 26. (30% is the increase from 20 to 26)

**What plus P% is Y?**

The above problem can be written in equation format :

X + X * P% = Y

X (1+P%) = Y

X = Y/(1+P%)

**What plus 30% is 26?**

- X = 26/(1+30%)
- X = 26/(1+0.30)
- X = 26/1.3
- X = 20

Therefore 20 plus 30% is 26.

**X minus P% is What?**

The way to ask the same question is What is the P percentage decrease from X?

The above problem can be written in equation format :

X – X * P% = Y

X (1 – P%) = Y

Y = X * (1 – P%)

**20 minus 30% is what? or what is 30% decrease from 20?**

- Y = 20 * (1 – 30%)
- Y = 20 * (1 – 0.30)
- Y = 20 * 0.7
- Y = 14

There fore 30% decrease from 20 is 14 or 20 minus 30% (6 is 30% of 20) is 14

**X minus What % is Y?**

The way to ask the same question is What is the percentage decrease from X to Y?

The above problem can be written in equation format :

X – X * P% = Y

X*P% = X – Y

P% = (X – Y)/X

P% = X/X – Y/X

P% = 1 – Y/X

**20 minus what percentage is 15? or what is percentage decrease from 20 to 15?**

- P% = 1 – 15/20
- P% = 1 – 0.75
- P% = 0.25
- P = 25%

There fore 25% decrease from 20 is 15 or 20 minus 25% (5 is 25% of 20) is 15

Therefore 20 minus 25% is 15. (25% is the decrease from 20 to 15)

**What minus P% is Y?**

The above problem can be written in equation format :

X – X * P% = Y

X (1 – P%) = Y

X = Y/(1 – P%)

**What minus 30% is 26?**

- X = 26/(1 – 30%)
- X = 26/(1 – 0.30)
- X = 26/0.70
- X = 37.14

Therefore 37.14 plus 30% is 26.
