What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and also ‘×’ and ‘÷’ are interchanged?
154 × 11 − 24 ÷ 3 + 19 = ?

To solve the given equation, we need to apply the specified interchanges of operators and then evaluate the expression using the BODMAS/PEMDAS rule (Bracket, Of, Division, Multiplication, Addition, Subtraction).

The given equation is:
154 × 11 − 24 ÷ 3 + 19 = ?

According to the problem description, we must make the following interchanges:
1. '+' and '–' are interchanged (i.e., + becomes −, and − becomes +).
2. '×' and '÷' are interchanged (i.e., × becomes ÷, and ÷ becomes ×).

Applying these interchanges to the original equation, we get the new equation:
$154÷11+24\times 3-19=?$

Now, we evaluate this expression step-by-step:

Step 1: Perform the Division
Divide 154 by 11:
$154÷11=14$
Substitute this back into the equation:
$14+24\times 3-19=?$

Step 2: Perform the Multiplication
Multiply 24 by 3:
$24\times 3=72$
Substitute this back into the equation:
$14+72-19=?$

Step 3: Perform the Addition and Subtraction
Add 14 and 72:
$14+72=86$
Now, subtract 19 from 86:
$86-19=67$

Thus, the value that comes in place of '?' is 67.

Therefore, the correct option is 67.
