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.

sir you are just giving two examples for each section please include some more questions thanks in advance :)

ReplyDeleteyes sir plz....

DeleteHow did you get 2x-4y = 16

ReplyDelete2(x-2y)=16

Deletex-2y=16/2

x-2y=8

x=8 -2y=8

x=8 y=-4

buddy u are wrong....can u explain how u got the value...when there are two unknown variables...we cant find the values of both....

DeleteUse factorisation method

Deleteyou got 2y-4x=16 as

Delete16 means Difference in years 1992 and 2008 ( its 16 yrs ) and

2y= age in 2008

4x= age in 1992

So Take a difference 2y-4x ( For current age ) thats equal to difference in time period i.e, 16 yrs

please include some more examples .......

1. kalyanis present age is if X than equation comes as X= (X-6)*5/4 so the value of X= 30 like wise age of her son wl b 30*1/10= 3 yrs

ReplyDeleteHi. Can you please explain, in example 2, from where we get this 16?

ReplyDeletegud eve sir i`m not understanding the age problem so plzzz can u explain breifle...

ReplyDelete2.Mahesh is as much younger to Anil as he is older to Prashant. If the sum of the ages of Anil and Prashant is 48 years,
