Seats for Mathematics, Physics and Biology in a university are in the ratio 5: 7: 8, There is a proposal to increase these seats by 40% , 50% and 75% respectively. what will be ratio of increased seats? Correct Answer 2: 3: 4
Let, the number of seats for Math, physics, and biology, be 5x, 7x and 8x respectively Number of increased seats are ( 140% of 5x). (150% of 7x) ( 175% of 8x) = (140/100×5x) , ( 150/100×7x), ( 175/100×8x) 7x, 21x/2, 14x The required ratio = 7x : 21x/2 : 14x = 14x : 21x : 28x = 2 : 3 : 4
