If 11.25 m of a uniform steel rod weighs 42.75 kg. what will be the weight of 9 m of the same rod?	Choose the correct answer.
A) 22.8 kg
B) 34.2 kg
C) 28 kg
D) 26.5 kg
E) none of these

Rationale: "explanation : let the required weight be x kg . then , less length , less weight ( direct proportion ) = > 11.25 : 9 : : 42.75 : x = > 11.25 x x = 9 x 42.75 = > x = ( 9 x 42.75 ) / 11.25 = > x = 34.2 answer : b"
Answer: B
