Question

Two clocks are set right at 10 a.m. One gains 20 seconds and the other
loses 40 seconds in 24 hours. What will be the true time when the first
clock indicates 4 p.m. on the following day?​

Answer 1

Answer:

There you go .

Step-by-step explanation:

From 10 am to 4 pm on the following day = 30 hours

Now, 24 hours 20 seconds of the first clock = 24 hours of the current clock.

∴ 1 hour of the first clock = 24 x 180 hours

4321

∴ 30 hour of the first clock = 24 x 180 x 30 hours

4321

Now, 24 x 180 x 30 hours = 29 hours 59 2521 minutes

4321 4321

∴ When the first clock indicates 4 pm on the following day the true time will be

3 hours 59 2521 minutes.
