If 8 loggers can chop down 28 trees in one day, how many trees can 20 loggers chop down in one day?
اگر 8 لوگر ایک دن میں 28 درختوں کو کاٹ سکتے ہیں تو 20 لاگرز ایک دن میں کتنے درخت کاٹ سکتے ہیں؟
Answer: 70 trees
Explanation
Choice C is correct. This is a proportion problem. If x is the number of loggers needed to chop down 20 trees,
then we form the proportion 8 loggers : 28 trees =20 loggers : x trees, or 288=x20. Solving for x, we get x=8(28)(20), or x=70
