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