a man purchased some eggs at 3 for rs 5 and sold them at 5 for rs 12.thus he gained rs 143 in all.the number of eggs he bought is?

• C.P. of 3 eggs = 5
  C,P, of x eggs = 5/3*x
  S.P. of 5 eggs = 12
  S.P. of x eggs = 12/5*x
  profit = S.P. - C.P.
  143 = 12/5*x - 5/3*x
  x = 195

• 3 eggs for rs 5
  1 egg c.p=5/3
  5 eggs s.p= 12
  1 egg s.p=12/5
  profit=12/5-5/3 for one egg
  = 11/15
  for x eggs profit =(11x)/15
  (11x)/15=143
  x=195
