Question

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 1

The new ratio will be
(5*1.4) : (7*1.5) : (8*1.75)
Or 7 : 10.5 : 14
To make them all whole numbers multiply them by 2 (because there is .5 after the 10)

Result: 14 : 21 : 28
