<p><strong>Divisibility by 5:</strong>The unit’s place digit is 1. Therefore, 961 is not divisible by 5.</p>
35
<p><strong>Divisibility by 7:</strong>Double the last digit (1 × 2 = 2) and subtract it from the rest of the number (96 - 2 = 94). Since 94 is not divisible by 7, 961 is not divisible by 7.</p>

<p><strong>Divisibility by 7:</strong>Double the last digit (1 × 2 = 2) and subtract it from the rest of the number (96 - 2 = 94). Since 94 is not divisible by 7, 961 is not divisible by 7.</p>
36
<p><strong>Divisibility by 11:</strong>In 961, the difference between the sum of the digits in odd positions and even positions is 6 - 1 = 5. Therefore, 961 is not divisible by 11.</p>
