Clearly, we have : (3 x 5) + 1 = 16 , (16 x 5) + 1 = 81 , (81 x 5) + 1 = 406
So, aliasing number = (406 x 5) + 1 = ?

Correct Option: D

Clearly, we have : (3 x 5) + 1 = 16 , (16 x 5) + 1 = 81 , (81 x 5) + 1 = 406
So, aliasing number = (406 x 5) + 1 = ?
∴ ? = 2031

The arrangement i* : 5 + 3 = 8 , 8 + 4 = 12 ,
So , ? + 1 = 13

Correct Option: C

The arrangement i* : 5 + 3 = 8 , 8 + 4 = 12 ,
So , ? + 1 = 13
∴ ? = 13 - 1 = 12
So. the missing number is 12.

Clearly, we have : 15 x 2 =30 , 2 x 7 = 14 , 7 x 9 = 63.
So, missing number = 9 x 1 5 = ?

Correct Option: C

Clearly, we have : 15 x 2 =30 . 2 x 7 = 14, 7 x 9 = 63.
So, missing number = 9 x 1 5 = ?
∴ ? = 135.

The given figure contains numbers 1 to 6 in three alternate segments, the smaller number being towards the outside and the numbers 14 to 19 in the remaining three alternate segment s with the smulle- number towards the inside.

Correct Option: B

The given figure contains numbers 1 to 6 in three alternate segments, the smaller number being towards the outside and the numbers 14 to 19 in the remaining three alternate segment s with the smulle- number towards the inside.

The two ends of each line segment contain a number and its square.
We have , 2² = 4
5² = 25
8² = 64
So, missing number = 1² = ?

Correct Option: A

The two ends of each line segment contain a number and its square.
We have , 2² = 4
5² = 25
8² = 64
So, missing number = 1² = ?
⇒ ? = 1
