Answer:PLEASE MARK MY ANSWER AS BRAINLIEST
Step-by-step explanation:
Heyyy...
Your answer is here.
Let boys = 7x
and girls = 5x
so total = 12x
Total students before new addmission = 12x = 1440
x = 120
boys = 7x = 7×120 = 840
girls = 5x = 5×120 = 600
Now new students addimitted
boys = 840+40 = 880
girls = 600+g
and the given ratio = 4:3
880/600+g = 4/3
220/600+g = 1/3
600+g = 660
g = 660-600
g = 60
Thankyou Buddy.
