### How to Find the Percent of a Given Number?

To calculate the % of a given number so easily, please follow the below steps:

• Take the number, say x.
• Let the percent as p%.
• To find the formula is P% of x
• Now, write these as a proportion as $$\frac { P }{ 100 }$$ = $$\frac { ? }{ x }$$
• Finally, do cross multiplication and calculate the value of the “?” mark.

### Solved Examples on Percentages

1. What is 3 ⅓ of 60 km?

Solution :

Given expression is 3 ⅓ of 60 km

$$\frac { 3 ⅓ }{ 100 }$$ = $$\frac { x }{ 60 }$$

Now, Convert mixed fraction to improper fraction

$$\frac { 10 }{ 3 }$$/100 = $$\frac { x }{ 60 }$$

$$\frac { 10 }{ 3 }$$ x100 = $$\frac { x }{ 60 }$$

$$\frac { 10 }{ 300 }$$ = $$\frac { x }{ 60 }$$

Cross multiply and find the x value

300x = 10 . 60

300x = 600

x = $$\frac { 600 }{ 300 }$$

x = 2 km.

2. Find 41% of 400.

Solution:

Given is 41% of 400

Now find the % of a given number

41% of 400 = 41 × $$\frac { 1 }{ 100 }$$ × 400

= $$\frac { 41 }{ 100 }$$ × 400

= $$\frac { 41 × 400 }{ 100 }$$

= $$\frac { 16400 }{ 100 }$$ (Finally divide 16400 by 100 and get the result)

= 164.

3. What is the sum of the money of which 5 % of $750? Solution: Let the required sum of money be$m.

5 % of $m =$750

⇒ $$\frac { 5 }{ 100 }$$ × m = 750

⇒ m = $$\frac { 750 × 100 }{ 5 }$$

⇒ m = 15000

Hence, sum of the money = $15000. 4. Find 17% of$4500?

Solution:

Given expression is 17% of $4500 Now, convert 17% into decimal form Then write it as 0.17 x$4500

Multiply  17 × $4,500 =$76,500

Finally, keep the decimal point

Therefore the result for 17% of $4500 is$765.00

5. The price of a TV was reduced by 40% to $500. What was the original price? Solution: To find the original price, First, determine the percentage of the actual price by subtracting 40% from 100. Later, Product the final price by 100 ie., 500 x 100 = 50000. Now, divide the result by the percentage computed in step 1 above. Then, $$\frac { 50000 }{ 60 }$$ =$ 833.33

The actual price of a TV is \$ 833.33.
