The given bar graph represents the number of students who appeared in the board examinations in session 2017-18 and 2018-19. Study the graph and answer the question that follows.
What percentage is the total number of students who appeared in 2017-18 is less than the total number of students who appeared in 2018-19? (Correct to one decimal place)
Answer & explanation
Correct answer: option 4
Total number of students appeared in examinations in 2017-18
= 25 + 40 + 53 + 32
= 150
Total number of students appeared in examinations in 2018-19
= 30 + 48 + 64 + 38
= 180
Required percentage = \(\frac{180-150}{180 }\) × 100
= \(\frac{30}{180 }\) × 100
= 16.67%
= 16.7% (Correct to one decimal place)
