Question : Anita scored 36 marks out of 120 but later her teacher increased 6 marks for her. What will be the increase in her percentage?
Option 1: 6%
Option 2: 10%
Option 3: 8%
Option 4: 5%
Correct Answer: 5%
Solution :
Anita scored 36 marks out of 120.
Her percentage = $\frac{36}{120}×100=30$%
Later her teacher increased 6 marks.
Her new percentage $=\frac{36+6}{120}×100=\frac{42}{120}×100=35$%
Increase in percentage = 35% – 30% = 5%
Hence, the correct answer is 5%.
