What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged? 69 + 2485 × 5 − 912 ÷ 2 = ?
1396
Step 1 – Swap operators (+ ↔ −, × ↔ ÷):
\(69 - 2485 \div 5 + 912 \times 2\)
Step 2 – Apply BODMAS: \(2485 \div 5 = 497;\ 912 \times 2 = 1824\).
Step 3 – Add/subtract: \(69 - 497 + 1824 = 1396\).
Hence 1396, option 1.
