Seats for Mathematics, Physics and Biology in a school are in the ratio 5:7:8. There is a proposal to increase these seats by 40%, 50% and 75% respectively. What will be the ratio of increased seats?	Pick
A) 2:3:4  B) 2:3:8  C) 2:3:0  D) 2:3:1  E) 2:3:9
Originally, let the number of seats for Mathematics, Physics and Biology be 5x, 7x and 8x respectively. Number of increased sears are (140% of 5x), (150% of 7x) and (175% of 8x)   i.e., (140/100 * 5x), (150/100 * 7x) and (175/100 * 8x)   i.e., 7x, 21x/2 and 14x   Required ratio = 7x:21x/2:14x   = 14x : 21x : 28x = 2:3:4   2:3:4nswer: 2:3:4
