What is the rate of learning closest to?
Answer
12%
Explanation:
| Units(A) | Time per Unit(B) | Total time (A*B=C) | Average Time(C/A) | 
| 1 | 200 | 200 | 200 | 
| 2 | 152 | 352 | 176 | 
| 3 | 138 | 490 | 163 | 
| 4 | 130 | 620 | 155 | 
Learning is applied on Average Time.
So,
Learning = (200 - 176) / 200 = 12%
