Answer:
let the students in A be x and students in B be y
x - 10 = y
y + 10 = x
Hope this helps you dear !
Answer:
Let the number of students in classroom A be x Let the number of students in classroom B be y. If 10 students are transferred from A to B, then we have: x – 10 = y + 10 ⇒x – y = 20 …..(i) If 20 students are transferred from B to A, then we have: 2(y – 20) = x + 20 ⇒2y – 40 = x + 20 ⇒ -x + 2y = 60 …..(ii) On adding (i) and (ii), we get: y = (20 + 60) = 80 On substituting y = 80 in (i), we get: x – 80 = 20 ⇒x = (20 + 80) = 100 Hence, the number of students in classroom A is 100 and the number of students in classroom B is 80
