  1. 15 / 4 = 25 / x

    15x = 100

    x = 6.7 days

  2. 15 men -> 1 apartment/4 days

    => 5 men -> 1 apartment/12 days

    => 25 men -> 5 apartments/12 days

    So, if 25 men produce the foundations for 5 apartments in 12 days, then they will produce a foundation for ONE apartment in 12 days/5 = 2.4 days
