If 11.25 m of a uniform steel rod weighs 42.75 kg. what will be the weight of 10 m of the same rod?
Pick:
A) 38 kg
B) 25.6 kg
C) 28 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 : 10 :: 42.75 : x   =&gt; 11.25 x x = 10 x 42.75   =&gt; x = (10 x 42.75) / 11.25   =&gt; x = 38   38 kgnswer : 38 kg
