Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term. 16 : 69 :: 24 : ? :: 31 : 144

121 109 105 116

109

THE LOGIC; (1st number x5) - 11 = 2nd number) => 16 : 69; 16 x5 -11 = 69 => 31 : 144; 31 x5 -11 = 144 155 - 11 = 144 Similarly, => 24 : ? 24 x5 -11 = 109 Thus 109 is correct.
