Question : 71 of 100

Marks: +1, -0

30 men working 8 h per day can dig a pond in 16 days. By working how many hours per day can 32 men dig two same ponds, in 20 days?

6 h per day
7 h per day
5 h per day
8 h per day

Solution:

\M_{1}=30, \D_{1}=16, \H_{1}=8

\M_{2}=32, \D_{2}=20, \H_{2}=?

We know that,

\M_{1} \×\D_{1} \×\H_{1}=\M_{2} \×\D_{2} \×\H_{2}

30 \×16 \×8=32 \×20 \×{\H}_{2}

\H_{2}={30 \×16 \×8}/{32 \×20}

\H_{2}=6

h per day
