The black one says, 'We have 28 legs altogether.'

The green one says, 'We have 27 legs altogether.'

The yellow one says, 'We have 26 legs altogether.'

The red one says, 'We have 25 legs altogether.'

Its simple ... in this group we have only one speaking the truth. Therefore, 3 of the servants have 7 legs adding up to 21. The one speaking the truth could have either 6 or 8 legs; a total of 29 or 27. As a result, the one speaking the truth is the green servant.
