Percentage Word Problems with Answers

Example 1.
In a class of 30 students, 5 students are failed. What percentage of students are passed the examination?

Solution:

No. of students in the class=30
No. of students failed in the examination=5
No. of students who passed in the exam=30-5=25
Percentage of students who passed in the examination=25/30
=5/6=0.83=83%
Hence, 83% of students passed the examination.


Example 2.
In a survey of 100 people, 8 persons didn’t know how to ride a bike. What percentage could ride?

Solution:

No. of people participated in the survey=100
No. of people didn’t know riding a bike=8
No. of people could ride a bike=100-8=92
Percentage of people who could ride a bike=92/100=0.92=92%.
Hence, 92% of people could ride a book.


Example 3.
A man spends 70% of his monthly salary. If he saves 15000 every month. Find his monthly salary?

Solution:

Let his income be Rs x.
Expenditure=70% of x.
Savings=30% of x=15000
x=15000 × 100/30
=150000/3=50000.
Hence, his monthly salary is 50,000.


Example 4.
In a class of 50 students, 30% are boys. How many more boys should be admitted to the class so that girls now become 50% of the class?

Solution:

At first, no. of boys=50×30/100
=1500/100
=15
No. of girls=50-15=35
Let the number of boys admitted in the class be X.
Now total no. of students in the class=50+x
50% of (50+x)=35
50+x=35 × 100/50
50+x=3500/50
50+x=70
x=70-50=20
Hence, 20 more boys should be admitted so that girls become 50% of the class.


Example 5.
In a sports survey, students choose their favorite sport out of basketball, cricket, and Tennis. 1/5 choose basketball, 1/3 choose cricket.3 persons choose Tennis. Find how many people are there in the group?

Solution:

Let the people participated in the survey=X
Percentage of people who choose basketball=x/5
percentage of people who choose cricket=x/3
persons choose Tennis=3
x/5+x/3+3=X
lcm=15
3x+5x+45=15 x
8x-5x=45
3x=45
x=45/3=15
The number of people who participated in the survey is 15.


Example 6.
A player won 75% of matches. In his total career, he lost 50 matches. How many matches did he play overall?

Solution:

Let no. of matches he played=x.
No. of matches he won=75%
No. of matches he lost=100-75%=25%
Given that he lost 50 matches.
25% of x=50
x=50 ×100/25
=200
Therefore, He played 200 matches overall.


Example 7.
Ajay’s scored 70 marks in the examination. His friend got a 20% less score. Find how many marks were scored by his friend?

Solution:

Ajay scored marks in the examination=70
His friend got less score=20%
Marks scored by his friend=70 × 20/100
= 14
=70-14=56
Therefore, Marks scored by his friend=56.


Example 8.
For a candidate to clear the examination, he must score 50% marks. If Anil gets 80 marks and fails by 40 marks. Find out the total marks for the examination?

Solution:

Given, Marks obtained by Anil is 80 and failed by 40 marks.
Pass marks=80+40=120
Let the total marks be X.
50/100 × x=120
x=120 ×100/50
x=240
Therefore, the total marks for the examination are 240.


Example 9.
60% of a number is more than 40% of 1200 by 180. Find the number?

Solution:

(60/100)x-(40/100)*1200=180
3/5x-2/5*1200=180
3/5x-480=180
3/5x=180+480
3/5x=660
x=660 ×5/3=1100
Therefore, the number is 1100.


Example 10.
30 is subtracted from 50% of a number, the result is 80. Find the number?

Solution:

Let the number from which 50% get subtracted is x.
50%(x)-30=80
50/100(x)=80+30
1/2x=110
x=110 ×2/1=220
Hence, if 30 is subtracted from 50% of 220 the result obtained is 80.


Example 11.
Divya took a test and got 30 correct and 10 incorrect answers. Find the percentage of correct answers?
