1. If Elias makes a box every 5 minutes and Nadim takes minutes to make a box, what will be the ratio of the number of boxes produced by Elias to the number of boxes produced by Nadim if they work for 5 hours and 50 minutes?

  • A. 5 to 6
  • B. 5 to 6
  • C. 5 to 6
  • D. 5 to 6

Answer: Option D

Explanation:

5 hrs 50 mins = 5 x 60 + 50 = 350 minutes

Salam makes = 350/5 = 70 boxes

Kalam makes = 350/7 = 50 boxes

Ratio = 70 : 50 = 7 : 5
