A decade back US was greater than Japan in semiconductor production. They both contributed 22% to world’s semiconductor production ten years ago. Now Japan contributed 300% more and US contributed 200%more. Japan produce more semiconductors than US.
What is the minimum contribution of Japan a decade back?

• let US contribution be=U
  Japan contribution be=J
  so, U+J=22
  After 10 years, US contribution, 3U
  Japan contibution, 4J
  if, 10 years agao, U=12 & J=10 as U>J
  afer 10 years US contribution=3*12=36
  Japan contibution, 4*10=40.
  this is the minimum possible contribution of japan.
