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).

⇒ [(140/100) × 5x],[(150/100) × 7x] and [(175/100) × 8x]

⇒ 7x, 21x/2 and 14x.

⇒ The required ratio =7x : 21x/2 : 14x

⇒ 14x : 21x : 28x

⇒ 2 : 3 : 4
