A) 9
B) 36
C) \[4\frac{1}{2}\]
D) 8
Correct Answer: A
Solution :
\[\because \]10 men = 18 boys \[\therefore \] 15 men = 27 boys \[\therefore \] 15 men + 33 boys = 27 + 33 = 60 boys \[\therefore \] \[\frac{{{M}_{1}}{{D}_{1}}}{{{W}_{1}}}=\frac{{{M}_{2}}{{D}_{2}}}{{{W}_{2}}}\] \[\Rightarrow \]\[\frac{18\times 15}{1}=\frac{60\times {{D}_{2}}}{2}\] \[\therefore \]\[{{D}_{2}}=\frac{18\times 15\times 2}{60}=9\] daysYou need to login to perform this action.
