    A, B and C are employed to do a piece of work of Rs 529. A and B together are supposed to do \[\frac{19}{13}\] of the work and B and C together \[\frac{8}{23}\] of the work. What amount should A be paid?

    A) Rs. 315          

    B)                      Rs. 345

    C) Rs. 355           

    D)                      Rs. 375

    Correct Answer: B

    Solution :

        (B + C) do \[\frac{8}{23}\] of the work \[\therefore \] A does \[1-\frac{8}{23}\,=\frac{15}{23}\] of the work \[\therefore \] Ratio of A's share to (B + C)'s share \[=\frac{15}{23}:\frac{8}{23}\,=15:8\] \[\therefore \] A's share \[\frac{15}{23}\,\times \text{Rs}\,529\,=\text{Rs}\,345\]
