Data Sufficiency (DS) | Re: If Jill's average score for three games of bowling was 168, what was

Let Jill's 3 scores be\(a\) ,\(b\) &\(c\) where\(a≤b≤c\)

Given sum of scores\(= a+b+c=168*3\)

so the lowest score,\(a=504-b-c\)

Statement 1 implies that\(c=204\) so\(a=300-b\)

if\(b=200\) ,\(a=100\) and if\(b=150\) ,\(a=150\) . Hence we don't have a unique value.Insufficient

Statement 2 implies\(b+c=364\) , so\(a=504-364\) .Sufficient

OptionB
