Question

seats for Mathematics Physics and Biology in a school are in the ratio 5:7:8 there is a proposal to increase the seats by 40% 50% and 75% respectively what will be the ratio of increased seats

Answer 1

Let the seat of Math will be 5. physics be 7. Biology be 8. Seat increase in Math 40% of 5 = 5×40/100= 2. math seat after increase= 5+2=7. Seat increase in Physics= 50% of 7= 7×50/100=7/2. Physics seat after Increase= 7+7/2=21/2=10.5. Biology seat after increase= 75% of 8= 8×75/100=6. Biology seat after increase= 8+6=14. Ratio increase seat =7:10.5:14
