Question

There are 8 types of pant pieces and $9$ types of shirt pieces with a man. The number of ways in which a pair ($1$ pant, $1$ shirt) can be stitched by the tailor is

• A. $17$
• B. $56$
• C. $64$
• D. $72$

Answer 1

The correct option is D $72$

Each piece of pant can be paired with $9$ different pieces of shirt.
Now there are $8$ pieces of pant.
Taking one piece of a pant at time, there are $9$ ways to stitch it, since there are $9$ different pieces of shirt.
Hence, the total ways will be
$=8\times 9$
$=72$
