Age problems are one of the most common topics in IBPS, CAT, GMAT and other banks exams. Students waste lots of time in this question as it look very simple but when they start solving with triditional methods, it takes a lot of time. Today I am solving few solving with shortcut trick. In case of any problem, please comment below.
Best way to solve Age questions is to assume fixed period with which further conditions will be compared. For example taking 2000 as fixed year.
Application of this rule
Example 1
Raman's age after 15 years will be 5 times his age 5 years back. What is his present age ?
Solution - Let's assume right now it is year 2000
Age of Raman in 1995 = x
Age of Raman in 2015 = 5x
Present age of Raman (in 2000) = x+5 or 5x-15
we will solve these two equation to find x.
X= 5. Then Raman's present age becomes = x +5 = 10
Example 2
Rahul was 4 times old as his son 8 years back and he will be 2 times old as his son after 8 years. Calculate Rahul and his son's age.
Assume that currently it is year 2000.
In 1992 Rahul's age = 4x, Age of Rahul's son = x
In 2008 Rahul's age = 2y and Age of Rahul's son = y
Now we get two equations 2y - 4x = 16 and y - x = 16
By solving this equation x = 8, so Rahul' son's current age = 16 years and Rahul's age = 40 years.
