उत्तर दाखवा आणि स्पष्टीकरण

उत्तर: (A) 10:48 a.m.

स्पष्टीकरण

The clock runs 1450 minutes for every 1440 true minutes; 1740 clock minutes = 1728 true minutes = 28 h 48 min.

  • (A) बरोबर

    Correct: 29 clock-hours = 29 × 1440/1450 true hours = 28 h 48 min; 6 a.m. + 28 h 48 min = 10:48 a.m.

  • (B) चूक

    Wrong: the gain is proportional, not a flat 10 minutes.

  • (C) चूक

    Wrong: miscalculated.

  • (D) चूक

    Wrong: far too early.

  • (E) चूक

    Wrong: only one of the options A–D is correct.
