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.
8 :48 :: ? : 143 :: 15: 195
Answer & explanation
Correct answer: option 1
8 : 48 :: ? : 143 :: 15: 195
The logic followed here is :
Ist terrm × ( ist term - 2) = iind term
As
8 : 48
8 × (8 - 2)
= 8 × 6
= 48
And
15 : 195
15 × (15 - 2)
= 15 × 13
= 195
Similarly
? : 143
13 × (13 - 2)
= 13 × 11
= 143
