Q. How much does a watch gain or lose per day, if its hands coincide every 64 minutes?

(A) Gain 92 min

(B) Lose 9 min

(D) Lose 34 (5/11) min

Correct Answer - Option(D)

Explanation by: Mr. Dubey

55 min. spaces are covered in 60 min.
60 min. spaces are covered in (60/55 × 60) min = 65 5/11 min
Loss in 64 min = (65 5/11 - 64) = 16/11 min
Loss in 24 hrs= (16/11 × 1/64 × 24 × 60) min = 32 (8/11) min.
