  Let the total flowers in a basket be X.
  Jasmine: Roses is 3:7
  Number of roses = 21
  jasmine = 3/10 of x and roses =7/10 of x ……..(equation1)
  we know, number of roses, i.e. = 7/10 of x = 21
  therefore,
  X = 21*10/7
  X= 30
  Putting the value of X in equation 1
  Jasmine = 3/10 of 30
  Jasmine = 9
  and
  roses = 7/10 of 30
  Roses = 21.
