UP Police Constable Exam Model Paper 1

The pattern followed here is:

Alphabets	A	B	C	D	E	F	G	H	I	J	K	L	M
Positional value	1	2	3	4	5	6	7	8	9	10	11	12	13
Positional value	26	25	24	23	22	21	20	19	18	17	16	15	14
Alphabets	Z	Y	X	W	V	U	T	S	R	Q	P	O	N

According to the alphabetical positions of the letters,
1) CDE → C + 1 = D; D + 1 = E
2) GHI → G + 1 = H; H + 1 = I
3) STU → S + 1 = T; T + 1 = U
4) FED → F - 1 = E; E - 1 = D
Hence, ‘FED’ is the odd one out.
