A 10300 B.10030 C 1353 D 1352 E 1339
Some how I m getting 2239 answer....
1st no can be 234713 and last is 458513
After every 100 number last 2 digits repeat.
So range is 234713, 234813, ...... 458413, 458513
Total no=45852347 +1
=2239

I also 2239
for every 100 increase there is just one such case with tens digit as 1 and unit as 3 (13), so 458600 234700 = 223900/100(to find the number of hundred's) = 2239

Sorry guys.. I can't confirm the answer since I too don't have the OA. I also got the same answer but it is not there in the ans. choices. Wanted to see if I am taking wrong approach..

I get the same answer:
458,600  234,700 = 223,900 agreed
In ever 1,000, 1 in the tens and 3 in the units appears 10 times.
013
113
213
313
413
513
613
713
813
913
So in the first 223,000 1 & 3 appear 2230 + 9 = 2239

I chose E as soon as I calculated the last digit.
I would have looked like a fool if I had posted without reading ur responses

A. 10,300 B. 10,030 C. 1,353 D. 1,352 E. 1,339 There is one number in hundred with 1 in th tens digit and 3 in the units digit: 13, 113, 213, 313, ...
