Question

Evaluate the following expression :
$(2^2+1)\times ({10}^2÷4-20)$

• A. 25

Answer 1

The correct option is A 25
$(2^2+1)\times ({10}^2÷4-20)$

Evaluating the terms inside the
brackets as per rules of BODMAS,
we get:

$2^2+1=4+1=5$

${10}^2÷4-20=100÷4-20=25-20=5$

$⟹(2^2+1)\times ({10}^2÷4-20)$
$=5\times 5$
$=25$
