Step-by-Step Solution
The complete worked solution.
Every step explained — no skipped algebra.
Total number of students appeared in 2017-2018 = 25 + 40 + 53 + 32 = 150
Total number of students appeared in 2018-2019 = 30 + 48 + 64 + 38 = 180
Difference = 180 – 150 = 30
Students appeared in 2017-2018 is less by 30 than the students appeared in 2018-2019
Required percentage = 30/180 × 100 = 16.67% or 16.7% approximately
Final Answer: Option B — 20.5%
