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.
27 : 99 :: 21 : ? :: 13 : 43
Answer & explanation
Correct answer: option 1
Logic followed is:
(First number × 4) - 9 = Second number
27 : 99
(27 × 4) - 9 = 108 - 9 = 99
13 : 43
(13 × 4) - 9 = 52 - 9 = 43
Similarly,
21 : ?
(21 × 4) - 9 = 84 - 9 = 75
So , 75 is correct answer .
