A. 45
B. 40
C. 35
D. 30
Answer: Option D
Solution(By Examveda Team)
Let 'n' number of men can be withdrawn$$\eqalign{ & \frac{{\left( {{{110}_{{\text{men}}}} \times {{48}_{{\text{days}}}}} \right)}}{{\frac{3}{5}{\text{work}}}} = \frac{{\left( {110 - {\text{n}}} \right) \times 44}}{{\frac{2}{5}{\text{work}}}} \cr & \Rightarrow 110 \times 16 = \left( {110 - {\text{n}}} \right) \times 22 \cr & \Rightarrow 160 = \left( {110 - {\text{n}}} \right) \times 2 \cr & \Rightarrow {\text{n}} = 30 \cr} $$
