. 12345................45 when divided by 46,remainder?

• sorry the above ans is for other ques
  its solution is
  sum of no. till 45 by n(n+1)/2
  =45*46/2=1035
  now divide 1035 by 46...remainder is 1
  (this method always works when no. is given as series 1234...,then find the sum of numbers upto the last [eg: 45 here],divide this sum by the given number i.e. divisor )
  check it for other numbers..
  1234/4
  rem=2
  also from sum/4=10/4
  rem =2

• 8/(3 sqrt(3))
  
  let us suppose side of square and triangle be a and b res.
  in terms of R radius of circle,
  a=R sqrt(2) since (R=a/sqrt(2))...due to diagonal as diameter
  b=R sqrt(2) since (R=a/sqrt(3))...due to equilateral triangle
  now,
  
  area of square a^2
  -------------- = --------------
  area of triangle (sqrt(3)/4)*(b^2)
  
  puting values of a and b in th above we get
  area of square (R sqrt(2))^2
  -------------- = -------------------------
  area of triangle (sqrt(3)/4)*((R sqrt(3))^2)
  solving it,
  
  area of square 8
  -------------- = -----------
  area of triangle 3 sqrt(3)
