      @@schandacademy ​ Sir for question 24. the answer will be 285.. Because Number which are divisible by 5 or 7 are 313 but we need to exclude number divisible by 35 . We only want the numbers divisible by 5 or 7 but not by 35. So, we subtract the 28 numbers divisible by 35:
      313 - 28 = 285.
      Therefore 285 natural numbers less than 1000 are divisible by 5 or 7 but not by 35

    in que no 103 ,
    short cut is - 2004 divide by 4 will get remainder 3 (say golu).
    and unit digit of given question (13) is 3 (say bholu to three).
    hence bholu to the power golu is twenty seven i.e. (3 to power 3 is 27 )
    so unit digit is 7. therefore seven is answer..

      There's a formula for that one 1/6n x (n+1) (2n+1).... Substitute 9 in place of n you'll get 1/6 x 9 x 10 x 19 gives you 90x19 divided by 6 you'll get your answer
      For question 20 you have to know the Roman numerals, it's a late middle age of writing number, like( ii is 2)( iii is 3) (v is 5) here M is 1000, D is 500, C is 100, L is 50 , then arrange the sequence from big to small like so M>D>C>L
