Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
12 : 120 :: 20 : 360 :: 3 : ?
Answer & explanation
Correct answer: option 4
Pattern followed here is :
2nd number = (1st number ) × (1st number - 2 )
We have ,
12 : 120
2nd number = (12 ) × (12 - 2 )
= 12 × 10
= 120
& 20 : 360
2nd number = (20 ) × (20 - 2 )
= 20 × 18
= 360
Similarly ,
3 : ?
2nd number = (3 ) × (3 - 2 )
= 3 × 1
= 3
3 is correct answer .
