Answer:b

Step-by-step explanation:

While this problem seems confusing, the answer is rather simple.

All you have to do is the reverse of what they are asking.

This is, substract 8 to 60 and then divide by 4:

$60-8 = 52\\\frac{52}{4} = 13$

So the interval which 13 falls into is 10 to 20 and the answer is b.
