- 400th digit will be 4
399th digit will be 3
398th digit will be 2
397th digit will be 1
909=9*101
123412341234.....1234
the series consists of 100-1's,100-2's,100-3's,100-4's
sum=1000

- Taking 1st 4 digits
1234/909 and the remainder is 325
now 12341234/909 = remainder 650 = 2*325
so for 400/4 digits = remainder = 100*325 =32500/909=685
so, 685 is the answer

TCS Other Question
You and two friends are having an argument about which of you is the smartest, so you ask a Grand Master Logician (Mike) to set up a completely fair test to reveal the smartest amongst you. Mike shows all three of you 5 hats - two red and three black. Then he turns off the lights in the room, puts a single hat on each person's head (except his own), and hides the remaining two hats. When Mike turns the lights back on, each of you is able to see the hats on the other two people's heads, but you cannot see the hat on your own head. The winner is the person who first guesses the correct color of his own hat. Each person can guess only once. What is your strategy for winning the contest?
