Saraswathy  (10 years ago)

2) (10,2,-36) ( -7,-5,15) , (19,21,x)
10+2=12
12*-3=36

-7+2=-5
-5*-3=15

19+2=21
21*-3= - 63

Ans : -63



3) 175, 94, 188, 124, 376, 327, 1308, x

175 - 94 = 81 (ie) 9^2
188 - 124 = 64 (ie) 8^2
376 - 327 = 49 (ie) 7^2
1308 - x should be 36 ie 6^2

1308 - x= 36

x=1272


5) (1, 3, 3),( 2, 8, 10), (3, 4, 12),( 4, 8, x)

1 * 3 = 3
2 + 8 = 10
3 * 4 = 12
4 + 8 = 12

Ans : 12

I think the series would be 5, 1, 2, 8, 1, 0, 9, 2, 3, 14, 1, 3
5+1+2=8
8+1+0=9
9+2+3=14
14+1+3=18
Ans:18

anyone plz give solution for 1st series

Is this solution Helpfull? Yes | No   

amit phougat  (7 years ago)

4) 3, 2, 1, 4, 5, 1, 0, 6, 3.....?
ANSWER IS 2
This series has following pattern:
(3, 2, 1), (4, 5, 4), (5, 1, 0), (6, 3, ?).

Here obviously the missing digit is 2.

Logic: The first digit in every parenthesis (3, 4, 5, 6) are increasing by 1. The second digit in parenthesis are (2, 5, 1, 3). Here every digit is one more than two times of preceding digit - Only unit place digit is taken. For example, (2*2+1 = 5), (5*2+1 = 11, so 1 is taken), (1*2+1 = 3). Last digit in every parenthesis is one less than the second digit.
