Correct Answer: C
Solution :
\[\overset{\mathbf{Men}}{\mathop{_{x+6}^{x}\mathop{\uparrow }_{{}}^{{}}}}\,\] \[\overset{\mathbf{Days}}{\mathop{_{20}^{30}\mathop{\downarrow }_{{}}^{{}}}}\,\] x + 6 : x : : 30 : 20 \[\Rightarrow \] \[\frac{x+6}{x}=\frac{30}{20}=\frac{3}{2}\] \[\Rightarrow \] \[2x+12=3x\] \[\Rightarrow \] \[3x-2x+12\] \[\Rightarrow \] \[x=12\,\text{men}\]You need to login to perform this action.
