How many minutes does a watch lose per day, if its hands coincide every 64 minutes ?
Solution
Correct Answer: Option B
55 min. spaces are covered in 60 min.
60 min. spaces are covered in \(\frac{60}{50}\times60\) min. = \(65\;\frac5{11}\) min
Loss in 64 min. = \(65\;\frac5{11}-64\;=\;\frac{16}{11}\) min
Loss in 24 hrs = \(\frac{16}{11}\times\frac1{64}\times24\times60\) min = \(32\frac8{11}\) min
