We will discuss here how to solve the problems involving percentage.
Everyday life problems involving use of percentage:
1. In an examination of 75 marks, Richard got 60 % marks. How many marks did Richard get?
Richard got 60 % marks = 60/100 = 3/5
60 % of 75 marks = 3/5 × 75 = 15 × 3 = 45
Therefore, Richard got 45 marks.
2. Derek secured 18 marks out of 25 in a test. Express his marks as a percentage.
18 marks out of 25 can be written as 18/25
Therefore, percentage = 18/25 × 100 % = 72 %
3. A man earns $ 450 per month. He spends 70 % of his income. What does he save every month?
The man spends 70 % of his income.
He save (100  70) is 30% of his income.
His saving = 30 % of $ 450
= 30/100 × 450 = $ 135
4. What percentage is 300 g of 2 kg?
2 kg = 2 × 1000 = 2000 g
To find the percentage we write 300 g/2000 g × 100 = 15 %
5. A student has to secure 40 % marks to pass. He gets 50 makes and fails by 30 marks. Find the maximum marks?
The student gets = 50 marks
He fails by 30 marks
The marks required to pass = 50 + 30 = 80
Now we have to find out Maximum marks.
As 40 % of Maximum marks = 80
Maximum marks = 80 × 100/40 = 200.
