IIFT 2021 (23rd Dec)
No of persons who drink coke = 2x + 57/x
As the no. of persons who drink coke will be an integer so 57/x must be an integer so x can be 1, 3, 19 or 57.
No. of persons who drink neither fruit juice nor coke = 57/3x = 19/x this also should be an integer, so x= 1 or 19 only
When x=1, no. of persons who drink coke = 2+57 = 59
When x=19, no. of persons who drink coke = 38 + 3 = 41
