# 12 workers can complete a piece of work in 10 days . If the number of workers will be reduced to 1/3 rd of the original number. then how manu more days would be requird to complete the same work

$12$ workers can complete a piece of work $=10$

$\frac{1}{3}rd$ of original numbers of workers

$\frac{1}{3} \times 12 = 4$

The number of workers reduced then more no days required

$12 \times \frac{10}{4} = 30$

then required days

$30 - 10 = 20$ days

Hence, $= 20$ days more
