Answer:
Here , the 12ft steel rod can machine =24 tapered pins
the 1ft steel rod can machine=24/12=2 tapered pins
now, the 6ft steel rod can machine =2*6=12 tapered pins.
Therefore, 12 tapered pins can be made form a steel rod 6ft long.
12 tapered pins can be made from a 6ft long steel rod.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question
We have
Number of pins machined from a 12ft steel rod = 24
⇒ Number of pins machined from a 1ft steel rod = 24/12 = 2pins
Therefore,
The number of pins machined from a 6ft steel rod = 2 × 6 = 12 pins.
Hence, 12 tapered pins can be made from a 6ft long steel rod.
