Question

The method of finding solution by trying out various values for the variable is called

• A. Error method
• B. Trial and error method
• C. Testing method
• D. Checking method

Answer 1

The correct option is B Trial and error method

$\Rightarrow$ The method of finding solution by trying out various values for the variable is called $Trialanderrormethod.$

$\Rightarrow$ In this method, we often make a guess of the root of the equation.

$\Rightarrow$ We fine the values of L.H.S and R.H.S of the given equations for different values of the variable.

$\Rightarrow$ The values of the variable for which L.H.S = R.H.S is the root of the equation.
