(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.

Answer / jack

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

n(LUF)=U-N(LUF)'
=25-19
n(LUF)=n(L)+n(F)-n(L^F)
19=13+15-n(L^F)
n(L^F)=28-19
n(L^F)=9

from formulae n(aUb)=n(a)+n(b)-n(aRUb),so
n(aUb)=25-6=19,n(a)=13,n(b)=15,n(aRUb)=x,so now,19=13+15-x
28-19=9,so answer is 9

However, all of the inhabitants are either Fairies or Trolls and they all use a spell to appear humanoid so you cannot tell which is which. And the Faries always tell the truth and the Trolls always lie, but there is a slight complication, some of the Fairies have gone insane and always lie and some of the Trolls have also gone insane and always tell the truth. So here is your task: you must ask the first inhabitant that you come to ONE question and from that ONE question you must determine wether Atlantis is still around or not. What is the question that you must ask?

Ali Baba had four sons, to whom he bequeathed his 39 camels, with the proviso that the legacy be divided in the following way : The oldest son was to receive one half the property, the next a quarter, the third an eighth and the youngest one tenth. The four brothers were at a loss as how to divide the inheritance among themselves without cutting up a camel, until a stranger appeared upon the scene. Dismounting from his camel, he asked if he might help, for he knew just what to do. The brothers gratefully accepted his offer. Adding his own camel to Ali Baba's 39, he divided the 40 as per the will. The oldest son received 20, the next 10, the third 5 and the youngest 4. One camel remained : this was his, which he mounted and rode away. Scratching their heads in amazement, they started calculating. The oldest thought : is not 20 greater than the half of 39? Someone must have received less than his proper share ! But each brother discovered that he had received more than his due. How is it possible?
