conversations.value: The profit from a business transaction is shared among 2 business partners, Mike and Johnson in the ratio 2:5 respectively. If Johnson got $2500, how much will Mike have after spending some of his share on a shirt that costs $200?
  Solve it.

conversations.value: According to the ratio, for every 5 parts that Johnson gets, Mike gets 2 parts
  Since Johnson got $2500, each part is therefore $2500/5 = $500
  Mike will get 2*$500 = $1000
  After buying the shirt he will have $1000-$200 = $800 left
