Let x be the number of girls who got triple-scoop.  Then (14-x) girls got double scoop.  Add up the total scoops, equate it to 37 and solve for x.

ranga · Answer

x girls got 3 scoops each.  Total scoops = 3x
(14-x) girls got 2 scoops each.  Total scoops = (14-x) * 2
add the totals: 3x + 2(14-x) = 37
solve for x.
