Correct Answer :

Option E

1

Solution :

The correct option is 1.

Let the missing value in place of the question mark ‘?’ be represented by x.

The given equation is:

15×3+7×x+24÷6×2=60

To solve for x, follow the BODMAS/PEMDAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction):

Step 1: Perform the division operation first.
Evaluate 24÷6=4.

Substitute this back into the equation:

15×3+7×x+4×2=60

Step 2: Perform the multiplication operations.
Calculate 15×3=45 and 4×2=8.

Substitute these values back into the equation:

45+7x+8=60

Step 3: Combine the constant terms on the left-hand side.
Add 45+8=53:

53+7x=60

Step 4: Isolate the term containing x.
Subtract 53 from both sides of the equation:

7x=60-53

7x=7

Step 5: Solve for x.
Divide both sides by 7:

x=77=1

Thus, the value that comes in place of the question mark ‘?’ is 1.
