Select the option that is related to the third number in the same way as the second number is related to the first number.
4 : 41 : : 7 : ?
Answer & explanation
Correct answer: option 3
4 : 41 : : 7 : ?
The logic followed here is :
4 : 41
= 4 : [(4 + 1 ) × (4 + 4 )] + 1
= 4 : ( 5 × 8 ) + 1
= 4 : 41
Similarly
7 : ?
= 7 : [(7 + 1 ) × (7 + 7 )] + 1
= 7 : ( 8 × 14 ) + 1
= 7 : 113
