What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged? 304 × 19 − 101 + 23 ÷ 5 = ?
2
By interchanging the operations as per the given instructions:
- Replace ‘+’ with ‘−’, ‘−’ with ‘+’, and ‘×’ with ‘÷’, ‘÷’ with ‘×’.
The equation becomes:
304 ÷ 19 + 101 − 23 × 5.
Step-by-step calculation:
1. 304 ÷ 19 = 16.
2. 23 × 5 = 115.
3. 16 + 101 = 117.
4. 117 − 115 = 2.
Thus, the answer is 2.
