(A Venn diagram can easily confirm the answer below.)
6 out of 25 don't speak both Latin and French, so only 19 speak EITHER Latin OR French OR both.
25 - 6 = 19.
Of the 19 who speak either or both languages, 13 speak Latin, so 6 speak French but not Latin.
19 - 13 = 6.
Of the 19 who speak either or both languages, 15 speak French, so 4 speak Latin but not French.
19 - 15 = 4.
So out of the 25, we have:
6 who don't speak both Latin and French
6 who speak French but not Latin
4 who speak Latin but not French
Therefore, those who speak both Latin and French are 25 - 6 - 6 - 4 = 9.

Answer / santhosh
there are totaly 25 members , and 6 will not speak either so now 25-6=19 .now only 19 members will speak these two languages .
now 19-13=6 now this 6 members will speak only french.
and 19-15=4 now this 4 members will speak only latin.
hence 6+4=10,is the number who speak only french and latin.
hence 19-10=9 '9' members can speak both .here '9' is the answer.

Total is 25 but out of them 6 dont speak either.
Out of 19, 15 knows French so definately, 19-15=4 knows
Out of 19, 13 knows Latin so definately, 19-13=6 knows
Now 6+4=10 knows exactly French or Latin.
So, 19-10=9 knows both Latin and French
