five years ago the average age of monu's age that time and ninu's age that time will be 17 years. five years from now if the ratio of monu's age to ninu's age that time was 8:5, What is monu's present age?

• present age of monu and ninu is M and N.
  5 year ago avg age is 17 hence
  M+N-10=34
  M+N=24..............Equation1
  and M+5/N+5=8/5
  5M-8N=15...........EQ2
  AFTER solve eq1 and eq2
  answer is 16 year.
