FILL THE MISSING SERIES
This is a simple number series, logically, all you need is to +11 which is the difference between 13 & 24 on the first or left column to complete the pattern and you get this..
Solution :
13 = 111 = 13
13+11 = 112 = 24
24+11 = 113 = 35
35+11 = 114 = 46
46+11 = 115 = 57
57+11 = 116 = 68
68+11 = 117 = 79
79+11 = 118 = 90
As you can see, there is a missing series, the 68 =116, 79=117, most of the people got trick on this... The series problem is commonly used in entrance exams because this is also the best way to test how careful you are in analyzing problems.
Actually there is other solution for this, which is more logic., you need to add the 3 digits at the right column,ex.. 111 >> 1+1+1 = 3 and so on... and put it on the right side of 1 2 3 4 5 6 7 8 9 0. but it comes to 2 digit you need to carry it over . ex, 10 to 8 , you need to carry 1 to 8 to get an answer 90.
Solution :
1+1+1 = 3 > 13 =111
1+1+2 = 4 > 24 =112
1+1+3 = 5 > 35 =113
1+1+4 = 6 > 46 =114
1+1+5 = 7 > 57 =115
1+1+6 = 8 > 68 =116
1+1+7 = 9 > 79 =117
1+1+8 = 10 > 90 =118
Solution :
1+1+1 = 3 > 13 =111
1+1+2 = 4 > 24 =112
1+1+3 = 5 > 35 =113
1+1+4 = 6 > 46 =114
1+1+5 = 7 > 57 =115
1+1+6 = 8 > 68 =116
1+1+7 = 9 > 79 =117
1+1+8 = 10 > 90 =118
The Correct Answer is 90.
