(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.
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

Answer / g hussain
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
| Is This Answer Correct ? | 7 Yes | 0 No |
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

The son of a rich bullion merchant left home on the death of his father. All he had with him was a gold chain that consisted of 138 links. He rented a place in the city center with a shop at the lower level and an apartment at the upper level. He was required to pay every week one link of the gold chain as rent for the place. The landlady told him that she wanted one link of the gold chain at the end of one week, two gold links at the end of two weeks, three gold links at the end of three weeks and so on. The son realized that he had to cut the links of the gold chain to pay the weekly rent. If the son wished to rent the place for 138 weeks, what would be the minimum number of links he would need to cut?

At the entrance to a members club stands a stranger seeking admission. A friend told him that it's easy to get in. You just have to answer a question corrcetly! Answering wrong, however, will result in being shot! To live a little longer, the man waits in a back alley near the entrance for people to go in. After a while a man comes to the entrance. The door warden asks him: "Twelve?" to which he replies "Six!" and goes in. "That's easy." our friend thinks, but he waits a little longer. Another man comes to the door. "Six?" the door warden asks, to which he replies "Three!" and goes in. "That's too good to be true" our friend thinks, and he was right. Because, when asked "Four?", he answered "Two!" and was found dead in the alley. What was the correct answer?
