Question

Answer 1

Answer:

34  times

Step-by-step explanation:

on a regular 12-hour digital clock how many times would be the same three digits in a row be displayed (e.g. 1:11,11:12,12:22) in one day​

One day = 24 Hrs

so we will find for 12 hrs & multiply it by 2

in 12 Hrs  Time is from 0 Min to 60 mins

1 : 11  , 2 : 22  , 3: 33  , 4 : 44 , 5 : 55  -   5 Cases

then

10 : 00  ,  12 : 22     -  2 Cases

11:10 , 11:11....................................,11:18 , 11:19     - 10 cases

5 + 2  + 10 = 17

Then 17 * 2 = 34  

34  times in  one day the same three digits in a row be displayed
