Correct Answer :

Option C

4312

43\frac{1}{2}

Solution :

To find the value of the given expression, we follow the order of operations (BODMAS/PEMDAS rule), which dictates that we perform division and multiplication (from left to right) before addition and subtraction.

The given expression is:
372 ÷ 56 × 7 - 5 + 2

Step 1: Perform the division first.
We can write the division 372÷56 as a fraction:
372 56
Both the numerator and denominator can be simplified by dividing them by their common factor, 4:
372 ÷ 4 56 ÷ 4 = 93 14

Now, substitute this back into the expression:
93 14 × 7 - 5 + 2

Step 2: Perform the multiplication.
Next, we multiply 9314 by 7:
93 14 × 7 = 93 × 7 14
Since 14 is divisible by 7 (14 = 2 × 7), we can simplify this calculation:
93 2

Substitute this value back into the expression:
93 2 - 5 + 2

Step 3: Perform addition and subtraction.
We calculate the remaining operations from left to right:
93 2 - 5 + 2 = 93 2 - 3

To subtract 3 from the fraction, we convert 3 to have a common denominator of 2:
3 = 6 2
Now subtract:
93 2 - 6 2 = 93 - 6 2 = 87 2

Step 4: Convert the improper fraction to a mixed number.
Divide 87 by 2:
87 divided by 2 is 43 with a remainder of 1.
Therefore, we can write:
87 2 = 43 1 2

Thus, the correct option is 4312.
