Question

If the hands of a clock coincide every 60 minutes, how much does it lose per day?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

55 min. spaces are covered in 60 min

60 min. spaces are covered in $(\frac{60}{55}\times 60)$ min. = 65$\frac{5}{11}$ min

Loss in 60 min. = $\left(65\frac{5}{11}-60\right)=\frac{60}{11}$min

Loss in 24 hrs = $\left(\frac{60}{11}\times 24\right)$min = 130$\frac{10}{11}$mins
