hi,

first 100 multiples of 10 are  10,20,,,,,,,,,,,,,,,,,,,,,,,,,,,,980,990,1000.

from 10 to 90 ,110 to 190 ,210 to 290 .....................................910 to 990 there are 90 zeros.

considering 100,200,300,.......................,800,900,1000. there are 21 zeros.

therefore the end product would have 90+21=111 zeros

ans:111 zeros.

plzz approve     !!! best of luck!!!!!
