• he total number of squares in a n x n chess board is equal to "the sum of first n natural number squares"
  i.e., n(n+1)(2n+1)6
  So Substituting 8 in the above formula we get 204

• L.c.m of 20,30,60=600units
  a can do 30 units
  b can do 20 units
  c can do 10units
  a(2 days)+a+b+c=120=3 days
  600/120=5*3=15 days
