B. 25 : 26

C. 28 : 25

D. 56 : 25

Answer: Option C

Solution(By Examveda Team)

The distance covered by policeman in 5 steps is equal to that of thief in 7 steps
⇒ 5P = 7T
P : T
7 : 5 (distance covered in each step)
⇒ And policeman goes 8 steps while thief moves 10 steps

		Policeman	:	Thief
Steps		8	:	10
Distance in each step		7	:	5
		56	:	50
Speed	=	28	:	25
