Question

If 11.25m of a uniform iron rod weighs 42.75 kg, what will be the weight of 6 m of the same rod? *​

Answer 1

Answer:

Correct option is A)

Weight of 11.25m of rod =42.75kg

Weight of 1m of rod =

11.25

42.75

=3.8kg

Weight of 6m of rod =3.8×6=22.8kg

Answer 2

Answer:

If 11.25m of a uniform iron rod weighs 42.75 kg, the weight of the 6m rod will be 22.8 kg.

Step-by-step explanation:

Weight of 6m rod = y

Length =11.25

Weight = 42.75

Length = 6

Weight = y

Ratio = 11.25 : 6 :: 42.75 : y

Product of extremes: Product of means

11.25y = 6 x 42.75

11.25y = 256.5

11.25/11.25 = 256.5

y = 22.8
