conversations.value: I need a clearer understanding of how to solve: Eliza buys 200 ornamental rings to sell in their local shop, twice the number of the remaining stock. After selling 3/4 of the total stock, her mother buys 300 more ornamental rings, and after three days, sells 150. What's the total number of ornamental rings remaining in the store?

conversations.value: If Eliza restocked twice the original number of ornamental rings, the number was 200/2= 100 rings.
  The total number of ornamental rings in stock is now 200+100 = 300 rings.
  When she sells 3/4 of the stock, the total number of rings sold is 3/4*300 =225 rings.
  The remaining stock is 300-225 = 75 rings.
  When her mother buys 300 more rings, the stock is boosted to 75+300 = 375 rings.
  She then sells out 150, reducing the stock to 375-150 = 225 rings
