Problems on Ages

Introduction

  •  If the current age is x, then n times the age is nx.
  •  If the current age is x, then age n years later, hence = x + n.
  •  If the current age is x, then age n years ago = x - n.
  • The ages in a ratio a: b will be ax and bx.
  •  If the current age is x, then \(1\over n\) of the age is \(x \over n\)
