Question

Suddenly, the number of problems the mathletes have to solve increases by 60%! To keep on track, the mathletes try to go faster but are only able to increase their speed by 25%. By what percent must the number of mathletes on the team increase so they solve all the problems in time, as scheduled?

Answer 1

Answer:

28%

Step-by-step explanation:

Lets say the fraction of speed and problem solved is 100/100

the number of problems solved increases by 60%

so now it is 160/100, also the speed increases by 25%

so now we do 160/125=1.28

finally we do 1.28-1 = 28%

Therefore the answer is 28%.
