    50 men can complete the work in 12 days.

    The same work needs to be completed in 50 days.

    Formula Used:

    For equal work

    M1×D1=M2×D2M_1 \times D_1 = M_2 \times D_2​​

    Solution:

    M1=50M_1 = 50 ​​ and D1=12D_1​ = 12​​

    M2=?M_2 = ?​ and D2=50 D_2 = 50​​

    50×12=M2×5050 \times 12 = M_2 \times 50​​

    M2=50×1250=12M_2 = \frac{50 \times 12}{50} = 12​​

    12 men are required to complete the work in 50 days.
