Show Answer
Correct Answer: (3)
Solution: (3) Number of students who opted for science stream in 2019
$=\frac{50 \times 110}{100}=55$
Total number of students (science and commerce streams) in $2015=52+80=132$
$\therefore$ Their number in 2019
$=\frac{132 \times 75}{100}=99$
$\therefore$ Number of students who opt for commerce stream in $2019=$ $99-55=44$
