Question

Compute the value of following expression $125\times 75$

• A. $325$
• B. $350$
• C. $375$
• D. $400$

Answer 1

The correct option is C

$375$

The given expression is

$125\times 75$

$=(100+25)(100-25)$

$=(100{)}^2-(25{)}^2\left[\right(x-y\left)\right(x+y)=x^2-y^2]$

$=1000-625$

$=375$
