Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term.
11 : 91 :: ? : 154 :: 15 : 127
Answer & explanation
Correct answer: option 2
Pattern followed here is :
First number × 9 - 8 = second number
Now, apply this pattern to given series
11 : 91
= 11 × 9 - 8
= 99 - 8
= 91 = second number
And,
15 : 127
= 15 × 9 - 8
= 135 - 8
= 127 = second number
similarly,
? : 154
= X × 9 - 8 = 154
X × 9= 162
X = 18
18 , is correct answer .
