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
Answer & explanation
Correct answer: option 2
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.
