The question is:
Seats for Math,Physics and biology in a school are in 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?
Apparently I am currently increasing 5 by 40% and 7 by 50% and 8 by 75% . But this is not giving the correct answer. Any suggestions what should be done here ??
