A is twice as good a work man as B and together they finish a piece of work in 36 days.The number of days taken by B alone to finish the work is : Options
A) 100 days .
B) 108 days .
C) 98 days .
D) 47 days .
E) 103 days .

Rationale: solution ( a ’ s 1 day ’ s work ) : ( b ’ s 1 day ’ s work ) = 2 : 1 . ( a + b ) ' s 1 day ’ s work = 1 / 36 divide 1 / 36 in the ratio 2 : 1 . ∴ b ’ s 1 day ’ s work = ( 1 / 36 x 1 / 3 ) = 1 / 108 hence , b alone can finish the work in 108 days . answer b
Answer: B
