-2

Show Answer

Correct Answer :

Option D

-2

Solution :

The correct answer is -2.

To find the value of p, we need to solve the given equation step-by-step using the BODMAS (or PEMDAS) rule, which dictates the order of operations: Division and Multiplication first (from left to right), followed by Addition and Subtraction.

The given equation is:

56 ÷ 4 + p × 3 - 24 ÷ 12 + 4 = 21 ÷ 3 + 3

Step 1: Perform the division operations on both sides of the equation.
On the left-hand side (LHS):
56÷4=14
24÷12=2
On the right-hand side (RHS):
21÷3=7

Substitute these values back into the equation:

14 + p × 3 - 2 + 4 = 7 + 3

Step 2: Simplify the multiplication and addition/subtraction.
Simplify the term p×3 to 3p.
Now simplify the constants on both sides of the equation:

LHS:
14 - 2 + 4 + 3 p = 16 + 3 p

RHS:
7 + 3 = 10

Step 3: Equate LHS and RHS and solve for p.

16 + 3 p = 10

Subtract 16 from both sides of the equation:

3 p = 10 - 16

3 p = - 6

Divide both sides by 3:

p = - 6 3

p = - 2

Therefore, the value of p is -2.
