UP Police Constable Exam Model Paper 3

The logic 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

The cube of the sum of the positional values of letters.
BD : 216 → B = 2 and D = 4 → 2 + 4 → 6${}^3$ ⇒ 216
Similarly,
EG : ? → E = 5 and G = 7 → 5 + 7 → 12${}^3$ ⇒ 1728
Hence, '1728' is the correct answer.
