If A denotes ‘÷’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘+’, then what will be the value of the following expression?
60 D 4 B 330 A 3 C 100 = ?

Correct option is B

Given: 60 D 4 B 330 A 3 C 100 = ?

As per the question after putting the signs we get following equation-
60 + 4 × 330 ÷ 3 - 100 = ?
Following the BODMAS rule (Bracket, Orders (i.e. powers and square roots, etc.), Division and Multiplication, Addition and Subtraction):
1. Division (÷): 60 + 4 × 110 - 100
2. Multiplication (×): 60 + 440 - 100
3. Addition (+): 500 - 100
4. Subtraction (-): 400
Final answer is (b) 400.
