If ‘+’ means ‘−’, ‘−’ means ‘×’, ‘×’ means ‘÷’ and ‘÷’ means ‘+’, what will come in place of ‘?’ in the following equation?
62 ÷ 12 × 3 - 8 + 5 = ?

Correct option is A

Given: 62 ÷ 12 × 3 - 8 + 5 = ?

As per the question after interchanging the signs we get following equation-
62 + 12 ÷ 3 × 8 – 5
Following the BODMAS rule (Bracket, Orders (i.e. powers and square roots, etc.), Division and Multiplication, Addition and Subtraction):
1. Division (÷): 62 + 4 × 8 – 5
2. Multiplication (×): 62 + 32 – 5
3. Addition (+): 94 - 5
4. Subtraction (-): 89
Final answer is (a) 89.
