Step 1
Acording to the given information,
Let the number of students in math123 be ‘x’
So, according to question in math136 there are 20% more students than math 123.
Number of students in math $136=480$
$480=\frac{20}{100}x+x$
Step 2
Now solve the above equation.
$480=\frac{20}{100}x+x$
$480=\frac{120x}{100}$
$\frac{480\left(100\right)}{120}=x$
$400=x$
Therefore, number of students in math123 are 400.
