1. An iron rod that weighs 24 kg is cut into two pieces so that one of these pieces weighs 16 kg and is 34m long. If the weight of each piece is proportional to its length. how long is the other piece?
- A. 11m
- B. 11m
- C. 11m
- D. 11m
Answer: Option B
Explanation:
given, A+B = 24
B = 8 and A = 16
also given weight = k * length ; k = weight /length
we get
K= 16/34
so for 8 kgs it would be
8 = k * length
8* 34/16 = length 17 m.
B = 8 and A = 16
also given weight = k * length ; k = weight /length
we get
K= 16/34
so for 8 kgs it would be
8 = k * length
8* 34/16 = length 17 m.
