If +, -, ÷, ×, =, > and < are denoted by Λ, V, Δ, , E, G, and L respectively, which of the following expressions is true?

If 'P' denotes '×', 'Q' denotes '÷', 'R' denotes '−' and 'S' denotes '+', then what will come in place of the question mark (?) in the following equation? 53 R 61 S 96 P 3 Q 2 S 28 P 6 R 99 Q 3 S 32 = ?

What will come in place of '?' in the following equation, if '+' and '-' are interchanged and '×' and '÷' are interchanged? 8 ÷ 2 + 14 × 7 - 7 = ?

If 'D' stands for '÷', 'E' stands for '×', 'F' stands for '+' and 'G' stands for '-', then what will come in place of the question mark (?) in the following equation? 24 E 2 D 4 F 5 G 3 = ?

If 'A' stands for addition, 'B' stands for division, 'C' stands for subtraction, and 'D' stands for multiplication, then what is the value of the following equation? 14 A 7 D 5 D (2 D 2) C (96 B 6) D 3 = ?

Choose the correct interchange of numbers which, when made in the equation, will make it mathematically valid: 9 + 4 ÷ 2 - 6 × 3 = 4 ÷ 3 × 6 - 9 + 1
