Answer: When metal M 3 is reacted with a salt of metal M 4 then it displaces metal M 4 from its salt solution and salt of metal M 3 is formed. But when metal M 4 is reacted with a salt of metal M 3, no reaction takes place.Hence, metal M 3 is more reactive than metal M 4, because it displaced metal M 4 from its salt solution but metal M 4 could not displace metal M 3 from its salt solution.
