Q. If Salam makes a box every 5 minutes and Kalam takes 7 minutes to make a box, what will be the ratio of the number of boxes produced by Salam to the number of boxes produced by Kalam if they work 5 hours and 50 minutes?

5 hrs and 50 mins = 350 mins

∴ Salam can produce in 350 mins = 350/5 = 70 boxes
and Kalam can produce in 350 mins = 350/7 = 50 boxes

∴ Salam : Kalam = 70 : 50 = 7 : 5 (Ans:)
 

Lets Robin's weight = 100 kg

As 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 kg

From all the above, it is clear that Marina weighs the least.
