In 8th grade class "G", there are enough underachievers, but Vovochka studies the worst of all. The pedagogical council decided that either Vovochka must correct his twos by the end of the quarter, or he will be expelled. If Vovochka corrects his twos, then 24% of the class will be underachievers, and if he is expelled, the underachievers will become 25%. What percentage of underachievers are there in 8 "G" now? #
Let there be $n$ students in the class. According to the condition, $0.24 n = 0.25(n-1)$, which means $0.01 n = 0.25$. Therefore, $n = 25$. One person constitutes $4\%$ of 25, so there are now $24 + 4 = 28\%$ of underachievers.

## Answer

$28\%$.
