CAT Question

A timer, having digits from 0 to 9 is replaced with a timer having digits from 0 to 4. Timers are used to count seconds. Hence, after the digit reaches a value of 4 in any position, it gets reset to zero and the digit to the left of this digit increases by 1. For example, at the completion of fourth second after the start, the counter will show 0004; but at the completion of fifth second it will show 0010. What will the counter show at the completion of 8th minute?
  • a)
    0013
  • b)
    0341
  • c)
    0143
  • d)
    1340
Correct answer is option 'B'. Can you explain this answer?
