In the following series, one of the terms given is wrong. Find that term and mark that as your answer. 102, 101, 98, 93, 86, 74, 66, 53
1. 101
2. 66
3. 74
4. 93
Answer: Option C
102 - 1 = 101
101 – 3 = 98
98 - 5 = 93
93 - 7 = 86
86 - 9 = 77
77 - 11 = 66
66 - 13 = 53
Therefore, 77 is the correct number which should replace the wrong number 74. So option C.

In a certain code RAJAN is coded as ‘91115’. How is IQBAL written in that code?
1. 98213
2. 27582
3. 12968
4. 18213
5. None of these
Answer: Option A
The question is related to the position of the letter in English alphabet. Since R comes at 18th position so its code is 1+8 = 9. A comes at 1st position and since it is a single digit number so it is coded as 1.similarly J = 10 is coded as 1+0=1 and A as 1and N=14 as 1+4 =5. So code for RAJAN is 91115. Similarly code for IQBAL is
I = 9
Q = 17 = 1+7 = 8
B = 2
A = 1
L = 12 = 1+2 = 3
Therefore, 98213 is required option.
Hence option A is the answer.
