Babul weighs twice as much as Akther. Akhter's weighs is 60% of Salam's weight. Ashraf weighs 50% of Hasan's weight, Hasan weighs 190% of Babul's weight. which if these 5 persons weighs the least?

Let Akhter and Babul's weight be A and B respectively. Then,  B = 2A       or, A = B/2 = 0.5B  And,  Hasan's weight = 190% of B = 1.9B Again, Ashraf weight = 50% of 1.9B = 0.95B Also, Akhter's weight is less than Salam's weight. So,  Akhter weighs the least.
