Correct Answer: B
Solution :
1 man = 2 women = 3 boys \[\therefore \] \[\text{1 man +1 woman + 1 boy = 3boys }\] \[\text{+ }\frac{3}{2}\text{boys + 1 boy}\text{.}\] \[\Rightarrow \] \[\frac{x}{55}=\frac{3}{11/2}\] \[\Rightarrow \] \[x=\frac{3\times 2}{11}\times 55=30\,\,days\]You need to login to perform this action.
