Seats For Mathematics, Physics And Biology In A School Are In The Rat

1.	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?
Answer» 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. 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.

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.
