Correct Answer :

Option B

85.5

85.5

Solution :

To find the value that should replace the question mark (?), we need to solve the given mathematical expression using the order of operations rule (BODMAS/PEMDAS):

The given expression is:
( 2 3 + 7 2 ) ÷ 2 × 3 = ?

Step 1: Simplify the terms inside the parentheses
First, evaluate the exponents inside the parentheses:
2 3 = 2 × 2× 2= 8
7 2 = 7 × 7 = 49

Now substitute these values back into the parentheses:
( 8 + 49 ) = 57

The expression now becomes:
57 ÷ 2 × 3

Step 2: Perform division and multiplication from left to right
First, divide 57 by 2:
57 ÷ 2 = 28.5

Next, multiply the result by 3:
28.5 × 3 = 85.5

Therefore, the value in place of the question mark is 85.5.
