Correct Answer - Option 1 : 5 γ 11

Given codes:

Symbols α β γ δ ρ
Operations + - × ÷ ^ 

 

Given expression: \(\left( {2\;\rho \;6} \right)\;\alpha 5\;\beta 7\;\gamma 4\;\delta 2 = \)

(2 ^ 6) + 5 - 7 × 4 ÷ 2

64 + 5 - 7 × 4 ÷ 2

64 + 5 - 7 × 2

64 + 5 - 14

69 - 14

55

Now let us check the options:

1. 5 γ 11

5 × 11 

55 → Correct 

2. 2 ρ (-3)

2 ^ (-3)

0.125 → InCorrect 

3. 15 δ 7

15 ÷ 7

2.14 → InCorrect 

4. 3 β 25

3 - 25

-23 → InCorrect 

Hence, 5 γ 11 is correct.
