(#M40002147) TCS QUESTION Keep an EYE

The citizen of a planet are 6 fingered and thus have developed a number system in base 6. a certain street in the planet contains 1000 buildings, numbered from 1 to 1000. how many 3's are used in numbering these buildings? express in base 10

Solution

The general fundamental for finding answer will be following
from 0 t0 9, 3 will come 1*(1) = 1 times
from 00 to 99, 3 will come 2*(10) = 20 times
from 000 to 999, 3 will come 3*(100) = 300 times
similarly others
now the following question is based on any other system so take the following steps
from 0 t0 9, 3 will come 1*(1) = 1 times
from 00 to 99, 3 will come 2*(6) = 12 times
from 000 to 999, 3 will come 3*(36) = 108 times
from 0000 to 9999, 3 will come 4*(216) = 864 times
