SOLVING ( BY UNITARY METHOD)
--------------------------------------------------

Length of wall built by 12 men in 6 days = 112 m

Length of wall built by 12 men in 1 day = 112/6 m

Length of wall built by 1 man in 1 day = 112/(6 × 12) m

Length of wall built by 25 men in 3 days = (112 × 25 × 3)/(6 × 12) m = 116.6 m
