Alam weight twice as much as Marina. Marina's weight is 60% of Robin's weight. Drabir weight 50% of Lina's weight. Lina weighs 190% of Alam's weight. Which of these 5 persons weighs the least?

Lets Robin's weight = 100 kgAs per question,Marina's weight = 60% X Robin's weight = 60% X 100 = 60 kg∴ Alam's weight = 60 X 2 = 120 kg∴ Lina's weight = 190% X 120 = 228 kg∴ Drabir's weight = 50% X 228 = 114 kgFrom all the above, it is clear that Marina weighs the least.
