Bricklayers

Seven bricklayers will build the house in 630 days. How many bricklayers do we need to take after 150 days to complete the building for (additional) 336 days?

Correct result:

n =  3

Solution:

MD=7 630   7 150+(n+7) 336=7 630  336n=1008  n=3MD=7 \cdot \ 630 \ \\ \ \\ \ \\ 7 \cdot \ 150 + (n+7) \cdot \ 336=7 \cdot \ 630 \ \\ \ \\ 336n=1008 \ \\ \ \\ n=3
