RRB Group D 2025 Question Paper (9-Aug-2026) (Shift 1)
The correct answer is

85

After interchanging ‘+’ with ‘−’ and ‘×’ with ‘÷’, the expression 40 ÷ 2 + 12 × 3 − 9 becomes 40 × 2 − 12 ÷ 3 + 9.

Following BODMAS: 40 × 2 = 80 and 12 ÷ 3 = 4.

So the value is 80 − 4 + 9 = 85.

Hence, the answer is 85.
