Example #2
P is as much younger to Q as he is older to R. If the sum of the ages of Q and R is 38 years. What is the present age of P?

  1. 12 Years
  2. 28 Years
  3. 32 Years

Q – P = X——-(1)
P – R = X——-(2)

From 1 and 2 we find
Q – R = 2X
Q + R = 38

So can’t determined

Answer: Option (B)
How to Solve
3X + 5 / 5X + 5 = 12 / 18
60X – 60 = 54X + 90
X = 5

Kunal’s present age is = 5 x 3 = 15 years.

Example #6
Lahiri is much younger than Partha as he is older than Kunal. If the sum of ages of Partha and Kunal is 65 years. Find the present age of Lahiri?

  1. 35 Years
  2. 65 Years
  3. 48 Years
  4. Data Inadequate

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (D)
How to Solve
( Partha – Lahiri ) = X…… (i)
( Lahiri – Kunal ) = X………..(ii)

So, We get from (i) and (ii)
Partha – Kunal = 2X
Partha + Kunal = 65

So, We can say that it can’t be determined.

Example #7
The sum of Pintu, Ajay and Nikhil’s age is 105 years. Five years ago the ratio of their ages was 4 : 6 : 8. What would be the present age of Nikhil?

  1. 35 Years
  2. 40 Years
  3. 45 Years
  4. 50 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (C)
How to Solve
4X + 5 + 6X + 5 + 8X + 5 = 105
18X = 105 – 15
X = 90 / 18 = 5

So, Five years ago Nikhil’s age was ( 5 x 8 ) = 40 years.
Nikhil’s present age is ( 40 + 5 ) = 45 years.

Example #8
Present age ratio of Ramesh and Suresh is 5 : 6 respectively. 6 years later the ratio of their ages will become 6 : 7 respectively. What is Ramesh present age in years?

  1. 30 Years
  2. 35 Years
  3. 25 Years
  4. 20 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (A)
How to Solve
Let, the present age of Ramesh and Suresh be 5X and 6X years respectively.
So, 5X + 6 / 6X + 6 = 6 / 7
7(5X + 6) = 6 (6X + 6)
36X + 36 = 35X + 42
X = 6

So, Ramesh’s present age is 5x = 5 x 6 = 30 years.

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (D)
How to Solve
6X + 5 + 8X + 5 + 12X + 5 = 171
26X = 171 – 15
X = 156 / 26 = 6

So, Five years ago Bijoy’s age was 6 x 8 = 48 years.
Bijoy’s present age is ( 48 + 5 ) = 53 years.

Example #11
Seven years ago the age ratio of Sonu and Monu was 6 : 5. 3 years later the ratio of their ages will be 11 : 10. What is Monu’s age at present?

  1. 15 Years
  2. 17 Years
  3. 20 Years
  4. 23 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Let, the age of Sonu and Monu 7 years ago be 6X and 5X respectively.
So, ( 6X + 7 ) + 3 / ( 5X + 7 ) + 3 = 11 / 10
10 ( 6X + 10) = 11 ( 5X + 10 )
5X = 10
X = 2

So, Monu’s present age is ( 5x + 7 ) = 17 years.

Example #12
Rahul would be thrice in 12 years as like Sanjay was 12 years ago. Now Rahul is 6 years senior than Sanjay. What is the present age of Sanjay?

  1. 8 Years
  2. 10 Years
  3. 12 Years
  4. 16 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (C)
How to Solve
Let, Sanjay’s present age is X years.
So, Rahul’s present age is ( X + 6 ) years.
( X + 6 ) + 12 = 3 ( X – 12 )
12X + 72 = 3X – 36
12X – 3X = – 36 – 72
9X = 108
X = 12.

The present age of Sanjay is 12 years.

Example #13
The total age of Golu, Sonu, and Bulu is 96 years. 10 years ago, the ratio of their ages was 2 : 4 : 5. What is the present age of Bulu?

  1. 40 Years
  2. 44 Years
  3. 48 Years
  4. 54 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (A)
How to Solve
Step 1: Let 10 years before Golu, Sonu, and Bulu’s ages are 3X, 4X and 5X respectively.
Then,
( 2X + 10 ) + ( 4X + 10 ) + ( 5X + 10 ) = 96
11X = 66
X = 6

Step 2: Bulu’s present age is ( 5X + 10 ) = ( 5 x 6 + 10 ) = 40 years.

Example #14
Ratio of ages of M and N before 4 years was 3 : 5. If the sum of present ages of M and N is 64 years. What is the present ages of M and N?

  1. 27 Years
  2. 39 Years
  3. 48 Years
  4. 60 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Step 1: M : N = 3 : 5 and M + N = 64 years.
Sum of both ages 4 years ago is ( 64 – 8 ) = 56

Step 2: M = ( 56 / 8 ) x 3 = 7 x 3 = 21 years
and N = (56 / 8 ) x 5 = 5 x 7 = 35 years.

Step 3: present age of M = ( 21 + 4 ) = 25 years
and present age of N = ( 35 + 4 ) = 39 years.

Example #15
At present, the ratio between the ages of Anil and Anu is 4 : 3. After 4 years, Anil’s age will be 24 years. What is the age of Anu at present?

  1. 5 Years
  2. 10 Years
  3. 15 Years
  4. 20 Years

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (C)
How to Solve
Let, the present age of Anil and Anu is 4X years and 3X years respectively.
So, After 4 years Anil’s age will be 24.
4X + 4 = 24
4X = 20
X = 5

So , Anu present age is 3X = 3 x 5 = 15 years.

      that means,whenever before/ago is there, actually we have to do ‘-‘ but in those particualr problems we are calculating for the present age,thats why whenever before/ago is used “converting into present age i.e ‘+’ is using”.
      for eg:In question if they give 5 years before/ago P’s age is twice of Q.
      In problem solvation they are converting into present age i.e P+5=2(Q+5)
