Problems on ages come both in bank
exams and SSC exams, but the frequency that is the number questions on problems
on ages is not very high. There are so many formulas on age problems which
definitely reduce your time in examination hall but what if you don’t remember the
formula at the time of exam or you can not recognize the formula? Well, this is
why I am sharing some tricks to solve problems on ages with question and
answers.
Q1. A father is twice as old as his son. 20 years
beck he was twelve times as old as his son. What is the present age of father?
Answer: Here I have tried to
explain the whole process graphically.

Then,
Figure 2 |
Now, here we have calculated that
the time period is 10, but we have been given that the time period is 20 years.
So
(20/10) * 22
[father’s present age
as derived in the figure above]
= 2 * 22 = 44 years.
Q2. 5 years ago, age of Sachin was
4 times the age of Vineet and after 10 years, Sachin will be twice as old as Vineet. Find the
present ages of Vineet.
Figure 4 |
Now, here we have found out the
total time period, from 5 years ago to 10 years after, which is 2. But
according to the questions the total time period is 15 years.
So, the present age of Vineet is
(15/2) * 1 + 5
= 7.5 + 5 = 12.5 years.
