- 121212121... upto 300digits / 99
12/99 => rem = 12
1212/99 => rem = 24 = 2*12
121212/99 => rem = 36 = 3*36
same way
121212121... upto 300digits / 99
121212121... upto 150 times 12 / 99 => rem = 150*12/ 99 => rem = 18 - 10 years agoHelpfull: Yes(8) No(4)

12*150/99 leaves remainder=18
so ans=18

- For 99 we've to make pair of 2digits and then sum up them
Here,(300/2)=150 pairs of 12s.
So,12*150=1800
hence, remainder is 18. - 10 years agoHelpfull: Yes(1) No(1)
