Select the option in which the numbers share the same relationship as that shared by the given pair of numbers. 72 : 14

36 : 19 92 : 17 45 : 20 81 : 80

45 : 20

72 : 14 The logic followed here is : Multiply the digits of ist number = IInd number As 72 : 14 7 × 2 = 14 BY checking all options 36 : 19 ⇒ 3 × 6 = 18 ≠ 19 92 : 17 ⇒ 9 × 6 = 18 ≠ 17 45 : 20 ⇒ 4 × 5 = 20 = 20 (correct) 81 : 80 ⇒ 8 × 1 =  8 ≠ 80
