Answer:
200 % is the answer.
Explanation:
Toni makes x be apple pies .
and Jane works for y hours.
therefore, he makes x apple pies in y hours
which implies he makes apple pies per hour
Now with help of an assistant:
Toni makes 60% more apple pies i.e. x + 0.6x = 1.6x apple pies
works 20% less i.e. y - 0.2y = 0.8y hours
therefore, now together they make 1.6x/0.8y apple pies per hour
simplifying we get
200
Hence % increase in output PER HOUR is 200.
