Question

The finance minister enters an incorrect value while calculating the product $25\times 19$.


Find the incorrect value.

• A. 200
• B. 108
• C. 50
• D. 45

Answer 1

The correct option is B 108

Find the result of $25\times 19$.

Now, $25=20+5$.
$19=10+9$.

Calculating $25\times 19$ using the box method, you get the following:


So, the correct value of the product $20\times 9$ is $180$ and "not" $108$.

Hence, the incorrect value in the given box method is $108$.
