Answer:
The seats for Maths • physics & Bio = 5:7:8
Let the nong seats be 511,782, 8X
Increase percentage = 40,50,75 Maths Seat = 5x + 40%-95x
= 5x+2x = 7x
Physich seat = 7x + 50%.97x =7X+3.5x = 10.5X
Biology seat = 8 x + 751-98x
= 8x+6x
= 140
So, New ratio of seals
=7x10.5x=148
That is 11.5:2 ok 2: 3:4
Hence, the ration of the increased seat will be 2:3:4
Step-by-step explanation:
Hence, the ration of the increased seat will be 23:40 1:15:2
