Question

Write multiplication table of $27$ using vinculum method and identify the number at sixth place.

• A. $108$
• B. $135$
• C. $162$
• D. $270$

Answer 1

The correct option is C $162$

We can write $27$ as $30-3$

In Vinculum method, instead of multiplying the number with $27$, its multiplied with $30$ and $3$ and the results are subtracted.

The multiplication table for $27$ is as shown in the figure.

Lets consider the sixth place,

$27\times 6=(30-3)\times 6=30\times 6-3\times 6=180-18=162$
