How much does a clock lose per day, if its hands coincide ever 65 minutes ?
A) 1440/143 min
B) 184/13 min
C) 1425/18 min
D) 541/9 min
Answer: C) 1425/18 min
Explanation:
55 min. spaces are covered in 60 min.
60 min. spaces are covered in ((60/55) x 60) min = 720/11 min.
Loss in 65 min. = (720/11 - 65 ) = 5/11
Loss in 24 hrs = (5/11 x 1/65 x 24 x 60)min = 1440/143 min.
