If 11.25 m of a uniform iron rod weighs 42.75 kg, what will be the weight of 6 m of the same rod?
Hint:
Hint:
Unitary methods: The unitary method is a method in which we find the value of a unit and then the value of a required number of units. For example, If 10 apples cost is 100 rupees, 1 apple will cost 10 rupees and if we are asked to find the cost of 100 apples, we can find it by multiplying 100 with cost of 1 apple.
The correct answer is: 22.8 kg
It is given that the rod is uniform which means the weight of the rod varies linearly with its length.
Given weight of 11.25 m rod = 42.75 kg
So, weight of 6 m rod = 
22.8 kg
Final Answer:
Hence, the weight of the 6 m rod is 22.8 kg.
