4. When Winnie-the-Pooh came to visit Rabbit, he ate 3 bowls of honey, 4 bowls of condensed milk, and 2 bowls of jam, and after that, he couldn't get out of Rabbit's burrow because he had become too fat from all the food. But it is known that if he had eaten 2 bowls of honey, 3 bowls of condensed milk, and 4 bowls of jam or 4 bowls of honey, 2 bowls of condensed milk, and 3 bowls of jam, he would have been able to leave Rabbit's burrow without any trouble. What makes him fatter: jam or condensed milk?
Answer: From condensed milk. Solution. According to the condition $3 m+4 c+2 v>2 m+3 c+4 v$, from which $\mathbf{~}^{+}+>2 v (*)$. According to the condition $3 m+4 c+2 v>4 m+2 c+3 v$, from which
$2 c>$ m+v. Adding the last inequality to the inequality (*), we get m +3 c $>$ m +3 v, from which c $>$ v.
