      Is it complete number system?

    1:24:00 A much quicker way to do it is just divide 111111 by 7 up to three digits(Six ones as all options have 5 digits and start with 1 so they won't exceed it)

    answer is (d) None
    2 occupies hundred and unit digit= 100+10+10 =120

    At 1.50.40 here option d would be correct because, sir had missed the counting of no. Between 202 to 292 ending with last digit by 2. Here also be 10 nos, so total would be 100+10+10=120 option d
    None of the above would be the correct option.

    Great session. Just noticed one mistake in Irrational no. Definition - the non- terminating repeating no.s are irrational. For example - 2.10100100010000.........
    Rational no.s include both terminating and non. terminating no.
    The difference is irrational no. include non-terminating repeating no. whereas rational no. includes non terminating (not repeating).

    401 to 500 = 21 times and 501 600 = 20 + 99
    then we add 21 + 20 + 99 = 140 times 5 will comes

    1:48:35 How many numbers are there between 100 and 300 which either begin or end with 2?
    Sol: 2 begins 100 - 199 = 0
    2 ends 100- 199 = 10
    2 begins 200- 299 = 99
    2 ends 200- 299 = 10
    Sum: ( 10+99+10) = 119
    Answer might be option d (none)
    Sir, you have not mentioned 2ends in 200-299 which resulted into 110.
    Or may be my sum is wrong.
    Respected @OnlyIasnothingelse team, I would be grateful if you clearify this.

    If option is from given one, then two of * should be at tens place. Like
    *+1*+2*+*3+*1= 21*
    22*=176
