Question 46

If 6 people working 8 hours a day can finish a work in 12 days, how many days will it take for 4 people working 8 hours a day to finish the same work?


Using $$M_1D_1H_1$$ $$=M_2D_2H_2$$

Let time taken be $$D_2$$

=> $$6\times8\times12=4\times8\times D_2$$

=> $$D_2=6\times3=18$$ days

=> Ans - (D)
