If 11.25 m of a uniform steel rod weighs 42.75 kg. what will be the weight of 8 m of the same rod?	Choose the correct choice:  A) 22.8 kg  B) 25.6 kg  C) 28 kg  D) 30.4 kg  E) None of these
Explanation :   Let the required weight be x kg. Then, Less length, Less weight (30.4 kgirect Proportion)   =&gt; 11.25 : 8 :: 42.75 : x   =&gt; 11.25 x x = 8 x 42.75   =&gt; x = (8 x 42.75) / 11.25   =&gt; x = 30.4   Answer : 30.4 kg
