PROBLEMS BASED ON AGES: <\/strong><\/p>\n

If the current age is x, then age n years later\/hence = x + n.<\/p>\n

If the current age is x, then age n years ago = x – n.<\/p>\n

If the sum of the ages of q persons is x, then n years later sum of the ages = x + nq<\/p>\n

If the sum of the ages of q persons is x, then n years ago sum of the ages = x \u2013 nq<\/p>\n

If the Average of the ages of q persons is x, then n years later average of the ages = x + n.<\/p>\n

If the Average of the ages of q persons is x, then n years ago average of the ages = x – n.<\/p>\n
