j + s + t = 150
s = 2j
and t = 30+s = 30+2j
j + s + t = 150
i.e. j + 2j + (30+2j = 150
i.e. 5j = 120
i.e. j = 24
Answer: Option B

If Jijil pays $j, the other two people pay $2j and $2j + 30. These three amounts sum to $150, so
j + 2j + 2j + 30 = 150
5j = 120
j = 24
j + 2j + 2j + 30 = 150
5j = 120
j = 24
