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 x 5x) , (150/100 x 7x) and (175/100 x 8x) => 7x, 21x/2 and 14x. So, The required ratio = 7x : 21x/2 : 14x => 14x : 21x : 28x => 2 : 3 : 4.Related questions
