The answer is 11 not any of those and I have proof.

anonymous · Answer

let x be the no of girls who took triple-scoop, so (15-x) girls took double-scoop
therefore
3x + 2(15 - x) = total no of scoops
=> 3x + 2(15 - x) = 36
=> x = 6
therefore 6 girls got a triple scoop

It's 11 I can prove it.

@Crazykid95 : i want to see your proof

anonymous · Answer

x + y = 15

x is number of girls who got double, y is number of girls who got triple.

2x + 3y = 36

Systems of equations.

x = 15 - y

2(15-y) + 3y = 36

30 - 2y + 3y = 36

30 + y =36

y = 6

6 girls got triple, 9 girls got double.
