Bullet Formulae to Solve problems on ages Quickly[Shortcut Tricks]:

  1. 1. The ration of present ages of Aand B is x:y. After a years from now,the ratio of their ages becomes  (x+1) : (y+1). Then their present ages are ax and ay

     Example: Ratio  of present ages of A and B is 2:3.After 6 years, ratio of their ages is 3:4.Find the present age                        of  A.

     Solution:        New Ratio        3:4

Old Ratio          2:3

Difference         1:1

present ages are (a/k)x and (a/k)y respectively.

     Example: The ratio of the ages of Ram and Sohan is 5:8. The ratio of their ages 10 years hence would be                              7:10. What is the present age of Ram ?.

     Solution:       New Ratio         7 : 10

                          Old Ratio           5 : 8

                          Difference           2 : 2

                         Difference = 2 ratio = 10 years => 1 ratio = 5 years

                         Ram’s Present age = 5 ratio = 25 years.


3.   Let ages of A and B are in the ratio a:b. After y years, the ratio of their ages becomes m:n. Then their present       ages are ax and bx years, whereeasemypreparaion-age-1

                  x = (Difference in the time * Difference in the new ratio)/(Difference in cross multiplication of new and                                                                                                                                                      old ratios)

     Example: Present age of Ram’s father is 4 times ram’s age. 5 years from now, father’s age will become 3                              times of Ram’s age, find present age of Ram’s father.

     Solution:                                     Father         Son

                            Old Ratio     =              4      :      1

                            New Ratio    =              3      :       1

                   Therefore    x = (5*(3-1))/(4*1-3*1) = 5*2/1 = 10 =>Father’s present age = 4*10 = 40 years.

4.   If ratio if age of a father and sum of ages of  n children is a:b. After k years, the ratio becomes c:d,                       the present  age of the father is ax and sum of ages of children is bx, where

     Example: Ratio of father’s age and sum of ages of his three children is 3:1. After 3 years, father’s age                                    will be twice of children’s age. Find the present age of the father.

     Solution:         Old Ratio = 3 : 1

                            New Ratio = 2 : 1

                                    x = (nc-d)k/(ad-bc) = ((3*2)-1)*3/3-2 = 15 => Father’s age 3x = 3*15 = 45 years.
