Answer 1

Answer:

students in older class is 80. Class difference is 100.

Step-by-step explanation:

let students in older class be x students.

Now, A.T.P. :

$2.25x = 180 \\ x = \frac{180}{2.25} \\ x = \frac{180}{225} \times 100 \\ x = \frac{12}{15} \times 100 \\ x = 80 \\number \: of \: students \: in \: his \: older \: class \: is \: 80. \\ class \: difference \: is \: 180 - 80 = 100 \: students.$
