Jalal weighs twice as much as Meena. Meena's weight is 60% of Bahar's weight. Dolly weighs 50% of Laila's weight. Laila weighs 19% of Jalal's weight. Who among these 5 persons weighs the least?

A) Bahar

B) Dolly

C) Jalal

D) Laila

E) Meena

Let's assign weights that meet the given conditions.

Meena's weight is 60% of Bahar's weightLet's let Bahar's weight = 100 kg

So, Meena's weight = 60 kg

Jalal weighs twice as much as Meena.Since Meena weight 60 kg (see above) then Jalal's weight = 120 kg

Laila weighs 19% of Jala's weightJalal's weight = 120 kg

19% is very close to 20%

20% of 120 kg = 24 kg

So, 19% of 120 kg =

a little less than 24 kg

So, Laila weighs

a little less than 24 kg

NOTE: At this point, we can see that, Laila is the lightest (so far!)

Dolly weighs 50% of Laila's weight.So, Dolly weighs LESS THAN Laila.

So, Dolly must weigh the least

Answer: D
