A) 3: 4: 5
B) 5: 7: 8
C) 5: 6: 8
D) 7: 8: 9
Correct Answer: C
Solution :
Work done by \[(A+B+C)=1\] Work done by \[(A+B)=\frac{11}{19}\] Work done by \[(B+C)=\frac{14}{19}\] Work done by \[A=1-\frac{14}{19}=\frac{5}{19}\] Work done by \[C=1-\frac{11}{19}=\frac{8}{19}\] Work done by \[B=\frac{14}{19}-\frac{8}{19}=\frac{6}{19}\] \[\therefore \] Required \[=\frac{5}{19}:\frac{6}{19}:\frac{8}{19}=5:6:8\]You need to login to perform this action.
