How many palindromes are there in a clock from noon to midnight ( For Example 5.45 is a palindrome)?

• 57
  after 12 o'clock 12:21.......=1
  from 1 to 9 it is 1.01, 1.11, 1.21, 1.31, 1.41, 1.51.= 6
  similarly 2.02,2.12,.................
  6*9=54+1=55
  after 10 o'clock 10:01, 11:11
  Ans: 55+2=57

• 57
  
  1.01, 1.11, 1.21, 1.31, 1.41, 1.51
  similarly upto 9 it has 54 palindromes and in addition to this 10.01, 11.11,12.21
  Therefore totally 57

• the ans is 57..because from 12:00 to 1:00 there are only one palindrome and this is 12:21.
  from 1:00 to 2:00 there are 6 palindrome this are 1:01,1:11,1:21,1:31,1:41,1:51
  so 2:00 to 3:00,3:00 to 4:00,4:00 to 5:00,5:00 to 6:00,6:00 to 7:00,7:00 to 8:00 ,8:00 to 9:00,9:00 to 10:00 also have 6 palindromes.
  from 10:00 to 11:00 have 1 palindrome and 11:00 to 12:00 have 1 palindrome..
  total no of palindrome=(6*9)+3=57

• ans 57
  after 12 o'clock 12:21.......=1
  from 1 to 9 it is 1.01, 1.11, 1.21, 1.31, 1.41, 1.51.= 6
  similarly 2.02,2.12,.................
  6*9=54+1=55
  after 10 o'clock 10:01, 11:11
  55+2=57

• 12 o'clock 12:21.......=1
  Consider 1'O clock it is 1.01, 1.11, 1.21, 1.31, 1.41, 1.51.= 6
  similarly 2.02,2.12,.................
  6*9=54+1=55
  after 10 o'clock 10:01, 11:11
  Answer: 55+2=57

• ans is 12
  becoz start with 1 so palindrome is--1.01
  for 2--2.12
  3--3.23
  4--4.34
  5--5.45
  6--6.56
  7--7.67(no such time)
  so from noon to midnight 6 palin+6 palin=12 palin

• from 1 to 9 will be 6*9+1*2(from 10 t0 12)=56 palindroms

• 57
  1.01,1.11,......1.51=6
  ly 2.02,2.12.....for 3,4,5,6,7,8,9
  6*9=54
  10:01,11:11,12:21
  54+3=57

• ans: 57
  12-1(12.21),
  1-6(1.01,1.11,1.21,1.31,1.41,1.51)
  2-6(2.02,2.12,2.22,2.32,2.42,2.52)
  3-6(3.03,3.13,3.23,3.33...
  .......
  9-6(9.09,9.19,9.29,9.39,9.49,9.59)
  10-1(10.01)
  11-1(11.11)

• 57
  after 12 o'clock 12:21 = 1
  from 1 to 9 it is 1.01, 1.11, 1.21, 1.31, 1.41, 1.51.= 6
  similarly 2.02,2.12,..
  6*9=54+1=55
  after 10 o'clock 10:01, 11:11
  Ans: 55+2=57
• 9 years agoHelpfull: Yes(0) No(0)
• 1.01,1.11,like that 6
  
  11*6=66
  66+1+2=69

• for every hour 6 times in 24 hours 24*6=144

• 57
  from 12 to 1 = 12:21--------=1
  after 1 till 9
  after 1= 1:01,1:11,1:21,1:31,1:41,1:51 --------=6
  similarly for 2 to 9
  hence ---------6*9=54
  after 10=10:01----------=1
  after 11=11:11-----------=1
  hence 1+54+1+1=57(ans).
