    pOoheaD-from long long time agoooOoooOOo...

    3) Some statements are given below:
    L says all of my other four friends have money
    M says that P said that exactly one among them has money
    N says that L said that precisely two among them have money
    O says that M said that three of the others have money
    P, L and N said that they have money
    All the above statement are false. Who has money & who doesn't
    have any money?

    P, L, and N say taht they have money, however, the statements are false, therefore, they don't have money.

    That leaves only M and O left.
    Let's test these results.

    L says that all his friends has money, appearantly that's wrong because only M and O has money.

    M says P says that exactly one amoung them has money, either M is wrong or P is wrong, and either way, that matches our estimation.

    N says that L said that 2 among them has money. Either N is wrong or L is wrong. In this case, if we assrue our guess is right, then N is lying.

    O says that M said that three of the otehrs have money, that would be wrong too.

    As we see, if these statements were all wrong, then that leaves M and O to have the money, and P L N don't have money.
