Clocks and Calendars Practice Test 1 with solutions

55 minutes spaces are covered in 60 minutes.
Minutes covered 60 minutes spaces
= $\left[\frac{60}{55}\times 60\right]$ minutes
= $65\frac{5}{11}$ minutes
Loss in 64 minutes = $65\frac{5}{11}-64$ = $\frac{16}{11}$ min
Loss in 24 hours = $\left(\frac{16}{11}\times \frac{1}{64}\times 24\times 60\right)$ min
= $32\frac{8}{11}$ minutes
