Question

To open gate B, Simplify the expression:

$8÷4÷2\times 3+7\times 2÷1-(8-5)$

• A. 11
• B. 12
• C. 13
• D. 14

Answer 1

The correct option is D 14

As per PEMDAS rule, parentheses come first.

Hence, we solve the expression inside the parentheses first.

$\to (8-5)=3$

The resulting expression becomes $8÷4÷2\times 3+7\times 2÷1-3$

Now comes the division and multiplication operations, starting from left to right.

$8÷4÷2\times 3+7\times 2÷1-3$
$=2÷2\times 3+7\times 2÷1-3$
$=1\times 3+7\times 2÷1-3$
$=3+7\times 2÷1-3$
$=3+14÷1-3$
​​​​​​​$=3+14-3$

Finally, we are left with addition and subtraction operations.

Let's solve these, one by one, starting from the left.

​​​​​​​​​​​​​​$3+14-3$
​​​​​​​​​​​​​​$=17-3$
​​​​​​​​​​​​​​$=14$

$\therefore$ The value of the given expression is $14.$
