If 11.25 m of a uniform steel rod weighs 42.75 kg. what will be the weight of 5 m of the same rod? Choose the correct choice from the following choices:
A) 22.8 kg B) 25.6 kg C) 19 kg D) 26.5 kg E) None of these
Explanation :   Let the required weight be x kg. Then, Less length, Less weight (Direct Proportion)   =&gt; 11.25 : 5 :: 42.75 : x   =&gt; 11.25 x x = 5 x 42.75   =&gt; x = (5 x 42.75) / 11.25   =&gt; x = 19   Answer : 19 kg
