Word problem on find percentage difference:
David lived in a United States of America. When David left the country the population was 920 million. David recently heard that the population has decreased by 6%. What is the present population?
Solution:
Find out the decrease percentage 920*6/100 = 5520/100 = 55.2 million
Then the new population is old population minus the decreased population
920-55.2 = 864.8 million
The population is now 864.8 million
Word problem 2:
Shan diets and decrease his weight 67kg to 65kg. Find the percentage decrease?
Solution:
Initially find the weight loss = 67-65 = 2kg
This 2kg is decrease the original weight. So the percentage will modify the original,
Let us take x as the decrease percentage
2=x * 67
Divide by 67 on both sides to make the variable alone
2/67 = 67x/67
0.0298 = x
Convert the decimal to percentage we get,
X=2.98%
The loss of weight in percentage is 2.98%
Understanding Sequence and Series is always challenging for me but thanks to all math help websites to help me out.
Word problem on find percentage difference
If 58 students in a class are boys and 42 students are in girls. Find the percentage difference between boys and girls?
Solution:
First find out the total number of students in a class
Boys + girls = 58+42 = 100
After that find out the percentage of boys in a class
Boys percentage = total number of boys / total number of students
= 58/100 = 58 %
After that find out the percentage of girls in a class
Girls percentage = total number of girls / total number of students
= 42/100 =42 %
Percentage difference = 58-42 =16
The girls are 16 % percentage lesser than boys
