Question

A, B and C together are employed to do a piece of work for Rs.529. A and B together are supposed to do $\frac{19}{23}$ 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
• E. None of these

Answer 1

The correct option is B

Rs.345

Work done by A = $(1-\frac{8}{23})=\frac{15}{23}$

$\therefore$ A : (B + C) = $\frac{15}{23}$ : $\frac{8}{23}$ = 15:8

So, A's share = Rs. $(\frac{15}{23}\times 529)$ = Rs. 345
