Here, in this Percentage worksheet, you will know about how to find the Percentage of the given values. This helps to practice for exams or any other competitive tests on the concept of finding Percent. Worksheet on Finding Percentage includes different types of questions with solutions. Let’s see some solved examples on finding percentage in the below. We have provided Step by Step Solutions for all the Problems so that it would be easy for you to understand the Concept of Percentages.
1. Find the percent of the following:
(i) 5 liters is 100 ml.
(ii) 600 ml is 3000 ml.
(iii) 15 kg is 450 g.
Solution:
(i) 5 liters is 100 ml.
The given value is 100 ml of 5 liters,
we know that 1 liter= 1000 ml, so we will convert liter to ml,
5 liters= 5—1000
= 5,000 ml,
so, to find the percent
100/5,000 — 100=
on solving, we will get the result as
= 2%.
(ii) 600 ml is 3000 ml.
The given value is 3000 ml of 600 ml, which means
600/3000 — 100=
on solving, we will get the result as
= 20%.
(iii) 15 kg is 450 g.
The given value 450g of 15 kg,
as we know 1 kg= 1000 g, so we will convert kg to g,
15kg= 15—1000 = 15,000 g
450/15,000 — 100=
on solving, we will get the result as
= 3%.
2. Figure out the value of X for the following below?
(i) 25% of X is 1000
(ii) 45% of X is 90 cm
(iii) 3.25% of X is 150 kg
Solution:
(i) 25% of X is 1000
We should find the value of X, so
Let the number be X,
As given 25/100 — X = 1000
1000/25 —100=
on solving, we will get 4000
So the value of X is 4000.
(ii) 45% of X is 90 cm
We should find the value of X, so
Let the number be X,
As given
45/100 — X = 90
90/45 —100=
on solving, we will get 200
So the value of X is 200 cm.
(iii) 3.25% of X is 150 kg
We should find the value of X, so
Let the number X,
As given
3.25/100 — X = 150
150/3.25 —100=
on solving, we will get 4,615.38
So the value of X is 4,615.38 kg.
3. What will be the number if 25% of the number is 4,500?
Solution:
Let the number X,
As given 25% of the number is 4,500, which means
25/100 — X = 4,500
4,500/25 —100=
on solving, we will get 18,000
So the number is 18,000.
4. Tom’s total compensation, in the wake of paying personal duty at 15 % is $86,240. Find his gross pay?
Solution:
Let the Tom’s gross income be X,
then (100-15)% of X = $86,240,
which means,
85% of X = $86,240,
on solving, we will get $101,458.82.
5. Mike secures 20 % of the maximum marks to pass. If Mike gets 20 marks and fails by 20 marks, then find the maximum marks.
Solution:
Let the Mike marks be X,
As he got 20 marks and failed 20 marks,
the pass marks are 20+20,
which is 40,
so to find the maximum marks,
20% of X= 40,
on solving, we will get 80.
So, the maximum mark is 80.
6. Tony bought 10 dozens of bananas from the fruit market, out of that 5% was spoiled. How many number of bananas are in a stable condition?
Solution:
The total number of bananas Tony bought is 10 dozens,
As we know 1 dozen= 12,
so 10 dozens= 120 bananas,
in that 25% of bananas are spoiled, which means
25/100 — 120=
on solving, we will get 30.
So, the number of bananas in a stable condition is
120-30= 90
Therefore, 90 bananas are in stable condition.
7. The total number of students in the class is 90 and in that 55 are boy students. What will be the percentage of girl students?
Solution:
The total number of students in the class is 90 students,
The total number of boy students is 55 students,
So to find the percent of boy students, first we need to find out the number of boy students,
which is 90-55= 35 students.
and the percentage of the boy students is=
35/90 — 100 =
on solving, we will 38.89%
So the percentage of boys is 38.89%.
