We need to count ones from 368 to 500.
Note: The digits of ones place are 0,1,2,3,4,5,6,8,9.
But when we count ones from 368 we will count 1 to 9 from number 368 because after 9 we gets 10 and that is tens.
On counting 368 till next 9 ones, we get --> 368+9 ones = 377.
Now again we will count next 9 ones from 377, we get --> 377+ 9 ones = 386
On keep going by this process, we will get following steps of counting onces.
386 + 9 ones = 395.
395 + 9 ones = 404.
404 + 9 ones = 413.
413 + 9 ones = 422.
422 + 9 ones = 431.
431 + 9 ones = 440
440 + 9 ones = 449.
449 + 9 ones = 458.
458 + 9 ones = 467.
467 + 9 ones = 476.
476 + 9 ones = 485.
485 + 9 ones = 494.
494 + 6 ones = 500.
In simple way, we can say that 386 + (12 * 9 + 6) ones = 500.
It can be read as after 386 counting 12 times 9 onces and one time 6 ones, we get 500.
