Answer 1

Answer:

Step-by-step explanation:Originally, let the number of seats for Mathematics, Physics and Biology be 5x, 7x and 8x respectively.

Number of increased seats are (140% of 5x), (150% of 7x) and (175% of 8x).

 {140 x 5x } ,  (150 x 7x)  and  {175 x 8x}  

                      100                                  100                                 100              

7x, 21x and 14x.

The required ratio = 7x : 21x : 14x

14x : 21x : 28x

2 : 3 : 4.
