RRB ALP CBT I Exam 14-Aug-2018 Shift 1 Solved Paper

Thirty men can do a piece of work in 16 days working 8 hrs a day. How many men are needed to complete another work, which is twice the first one, in 10 days working 12 hrs a day?
The following are the steps involved in solving the above problem. Arrange them in sequential order.
A) M₂ = $\frac{30\times 16\times 8\times 2\mathit{x}}{\mathit{x}\times 12\times 10}$
B) $\frac{30\times 16\times 8}{\mathit{x}}=\frac{{\mathit{M}}_2\times 12\times 10}{2\mathit{x}}$
C) $\frac{{\mathit{M}}_1{\mathit{D}}_1{\mathit{H}}_1}{{\mathit{W}}_1}=\frac{{\mathit{M}}_2{\mathit{D}}_2{\mathit{H}}_2}{{\mathit{W}}_2}$
D) M₂ = 64
