Anita scored 36 marks out of 120 but later her teacher increased it to 6 marks for her. What will be the increase in her percentage?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 5%
Given that
Anita scored 36 marks out of 120
Later, her marks increased by 6 marks,
According to the question
the initial percentage of marks = 36 × 100/120 = 30%
Now, her new marks = 36 + 6 = 42
Her new percentage of marks = (42/120) × 100 = 35%
Hence, the increased percentage of marks = 35 - 30 = 5%
