A) 6 months
B) 4 months
C) 5 months
D) 8 months
Correct Answer: B
Solution :
10 men = 20 women 1 man = 2 women = 5 children 1 woman = 2 children \[\therefore \] 5 men + 5 women + 5 children = 20 + 10 + 5 = 35 children \[\therefore \,\,{{M}_{1}}{{D}_{1}}={{M}_{2}}{{D}_{2}}\] \[\Rightarrow \,\,40\times 7=35\times {{D}_{2}}\] \[\Rightarrow \,\,{{D}_{2}}=\frac{40\times 7}{35}=8\]months Required time = 4 months.You need to login to perform this action.
