A, B and C are employed to do a piece of work for Rs.529. A and B together are supposed to do 19/23 of the work and Band C together 8/23 of the work. What amount should A be paid?

A.  Rs.315   
B.  Rs.345
C.  Rs.355   
D.   Rs.375
Answer:     B

Explanation :

Work done by A    = (1 - 8/23)
                              = 15/23
A : (B+C)    = (15/23 : 8/23)
                    = 15 : 8
So, A's share =Rs.(15/23 x 529)    

                     = Rs.345.
