#### Solution

Let A & B denote the sets of the persons who like Hindi & English, respectively.

$\text{ Given }:$
$n\left( A \right) = 750$
$n\left( B \right) = 460$
$n\left( A \cup B \right) = 950$

$n\left( A - B \right) = n\left( A \right) - n\left( A \cap B \right)$
$n\left( A - B \right) = 750 - 260 = 490$
$\text{ Thus, 490 persons can speak only Hindi } .$
