A) Rs.450
B) Rs.168.75
C) Rs.337.50
D) Rs.718.75
Correct Answer: A
Solution :
A's one day's work \[=\frac{1}{6}\] B's one day's work \[=\frac{1}{8}\] C's one day's work \[=\frac{1}{12}\] A's share: B's share: C's share \[=\frac{1}{6}:\frac{1}{8}:\frac{1}{12}\] Multiplying each ratio by the L.C.M. of their denominators, the ratios become \[4:3:2\] \[\therefore \] B's shared \[=\frac{1350\times 3}{9}=Rs.450\]
