it's a matrix type question.   i never did it that way though. i always used logic, but it woudl take longer than what it should . i believe one of those were on the test.     i know you know how to do 'em.

3 people mow 10 lawns in 20 hours.. so 1 person mows 3.33 lawns in 20 hours.   or 0.16666666 lawns in 1 hour

34 ppl = 34 * 0.16666667 lawns per hour = 5.66667 lawns/hr ...  100 lawns /  5.666667 lawns/hr = 17.64 hours?
