    Default A new government......How many are dumb?

    In a country (not far from here), a new Government has just been elected.

    Apparently (so I'm told)..... of the new members of parliament voted in, 90% are lame, 85% are deaf, 80% are blind and 75% are dumb.

    What percentage at least must be lame, deaf, blind and dumb?

    Since 90% are lame, 10% are not lame.
    Even allowing all of these to be deaf, there is an overlap of 75% at least, who must be lame and deaf.

    Similarly between these and the blind there is an overlap of 80-25 or 55% who must be lame, deaf and blind.

    Finally the overlap of these with the 75% dumb gives us 75-45 or 30% at least, who must be lame, deaf, blind and dumb.

    And I'll leave it there.

    Up to 35% can be either lame or dumb but not both; similarly, up to 35% can be either deaf or blind but not both. Which means that the minimum amount who can be all four is 30%

    So I agree with Greg.
    I may be weird, but I'm saving up to become eccentric.

    30% must be deaf blind lame and dumb
    75% could be deaf blind lame and dumb

    For every 100 pepole
    25 are not dumb
    20 are not blind
    15 are not Deaf
    10 are not blind

    thus
    70 ( max ) could be not deaf blind lame and dumb
    25 ( min ) could be not deaf blind lame and dumb
