Problems on Ages

Working methodology: In these problems, two persons initial ages will be given. and before or after several years, their ratio of the ages will be given.  Multiply the ratio of their initial age by x or some variable and take them as their initial age.  Now if final ratio has been given, equate this ratio with that ratio and find x.  Or proceed according to the problem.
