Solution:

Since MD = Constant
Where M = No. of men
D = No. of days for work
Initially

M_{1}=52

{D}_{1}=10

days.
Due to emergency, 12 men were sent. Thus, number of men remaining.

{M}_{2}=52-12=40

Now

52 × 10=40 × D_{2}

{D}_{2}=13

days
No. of days, more than original estimate

=13-10

=3

days
