Anita scored 36 marks out of 120 but later her teacher increased 6 marks for her. What will be the increase in her percentage?
Answer & explanation
Correct answer: option 4
Percentage of Anita when her score was 36 out of 120 = $\frac{36}{120}$ x 100 = 30%
Her percentage when scored increased by 6 marks i.e. her score became 42 = $\frac{42}{120}$ x 100 = 35%
Thus, Increase in her percentage = 5%
