Answer:
Nolan took 100 seconds to solve the test
Step-by-step explanation:
Kong took 15% percent fewer seconds than Nolan. Kong took 85 seconds
how long does it take 15% less time than it took Nolan
to suppose that the time that Nolan was taken corresponds to 100% of the time, as kong was taken 15% less than the time that Nolan then kong was taken 100-15 = 85% of the time that was taken, Nolan
Kong took 85 seconds corresponding to 85% of the time
Now if 85 seconds equals 85% to how many seconds 100% equals
We apply a simple rule of three
Nolan took 100 seconds to solve the test
