Best answer
Correct Answer - Option 3 : 68 : 54

The pattern followed here is,

For,

84 : 72

(First Digit of the first number) - 1 and half of the second number = 72 

(8 - 1) (4 ÷ 2) 

72 = 72.

Similarly,

For 77 : 64

(7 - 1) (7 ÷ 2)

6 (3.5) 

63.5 ≠ 64.

For 64 : 56

(6 - 1) (4 ÷ 2)

52 ≠ 56

For 68: 54

(6 - 1) 8 ÷ 2

54 = 54 

For 76 : 62

(7 - 1) (6  ÷ 2)

63 ≠ 62

Hence, the correct answer is "68 : 54".
