100. Palindromic numbers for the range 10000 to 20000 are 5 digits numbers of the form abcba. The first digit ('a') must be '1'. There are 10 possible digits for 'b' (0-9) and for each of these 10 possible digits for 'c' Thus there are 1 x 10 x 10 = 100 palindromic numbers between 10000 and 20000.
10201
30000
1000 = 1 secondso 10000 = 10 secondssp 20000 = 20 seconds
The answer is 20000. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
