Select the option that is related to the third number in the same way as the second number is related to the first number.
13 : 109 :: 24 : ?
Answer & explanation
Correct answer: option 3
The pattern followed here is second number = (first number × 8) + 5
109 = (13 × 8) + 5 = 104 + 5 = 109
Similarly,
? = (24 × 8) + 5 = 192 + 5 = 197
? = 197
Hence, 197 is the correct answer.
