the tax increases by 9% per year. What will be the cost of the shirt after 65 months and how much percentage loss for the people those who buy it

• cost of t-shrt after 65 mnthhs is 100(1.1)^5 = 161.051
  tax is 100(1.09)^ = 153.86
  and shpkpr adds 5 rs every yr ie,5*5 =25

  loss 340-100 =240
  loss % 240/100*100 =240%
