Key to this problem is calls are proportional.

total days = 20 + 19 + 17 = 56
total calls = 168

calls / day = 3

so in august 19 * 3 = 57

My take on this !

"the question says calls made were proptional to number od days worked"

and we need to find calls made on month of august and days worked is 19

so key here is the find the multiple of 19 and looking for the option in choices !

so we have 19*3 =57 on the first take

so in june it would be 20*3=60

july it is 17*3=51

51+57+60=168

OA = 57
