Question

Find $25\times 10$, using lattice method of multiplication.

• A. 250

Answer 1

The correct option is A 250
To find $25\times 10$ using lattice method of multiplication, we need $2\times 2$ rectangular table.

$25$ and $10$ will be arranged as shown in below figure,
Now, multiplying digits on top with the digits on the right of the rectangle one by one and place the ones digits of their product on left and tens digit on right of the diagonal as shown in below figure,
Now, adding the digits along the diagonals as shown in below figure,
Finally add the simplified digits from left to bottom in order to get the product as shown in below figure,
Therefore, $25\times 10=250$
