# Problem On Ages Tips, Tricks And Shortcuts

## Tips and Tricks to solve Problem on Ages

On this page you will get to know about all the tips, tricks and shortcuts on Problems on Ages and How to solve them easily using tricks and shortcuts.

## Important Formulas to Solve Ages Question

- If you are assuming the current age to be x, then the age after n years will be (x+n) years.
- If you are assuming the current age to be x, then the age before n years will be (x-n) years.
- If the age is given in the form of a ratio, for example, p:q, then the age shall be considered as qx and px
- If you are assuming the current age to be x, then n times the current age will be (x×n) years
- If you are assuming the current age to be x, then 1/n of the age shall be equal to (x/n) years

## Tricks to Solve Ages Question

- The most important thing is to read the question carefully and gradually form the equation which shall help you answer the question.
- Basic things like addition, subtraction, multiplication and division will help a candidate reach the answer and no complicated calculations are required to answer such questions.
- Arrange the values given by placing them correctly in an equation by giving variables to the unknown values
- Once the equation has been formed, solve the equation to find the answer.
- The final step is to recheck the answer obtained by placing it in the equation formed to ensure that no error has been made while calculating.

## Type 1:

### Tips and Tricks to solve Problems on Ages Based on Present Age

### Question 1.

**In the next 6 years, C will be double the age of D 6 years back. If at present C is 5 years elder to D, then find D’s present age.**

A.) 32

B.) 25

C.) 23

D.) 20

**Correct answer C**

**Explanation : **

Let D’s present age be x

Given, (x + 5) = C’s age

Given, (x + 5) + 6 = 2(x – 6)

= x + 11 = 2x – 12

x = 23

## Type 2:

### Tips and Tricks to solve Problems Based on Age Before K Years

### Question 2.

**Vikram said to his daughter, “I was as old as you are today when you were born.” If Vikram’s age is 45 today, then his daughter’s age 3 years ago was?**

A.) 22

B.) 19.5

C.) 23.5

D.) 21.5

**Correct answer B**

**Explanation : **

let vikram’s daughter age = z.

Given , 45- z = z .

So, 2z = 45 , z = 22.5.

So, 3 yrs ago, daughter age will be 22.5 – 3 = 19.5.

## Type 3:

### Tips and Tricks to solve Problem Based on Age After K Years

### Question 3.

**Lalita is four times the age of Om. If after 3 years, she would be three times of Om, then additional after 3 years, how many time would be her age of Om?**

A.) 2.5

B.) 3.5

C.) 2

D.) 3

**Correct answer A**

**Explanation :**

Let us assume Om’s age as s and Lalita’s age as 4s

Given, 4s + 3 = 3(s + 3)

= 4s + 3 = 3s + 9

s = 6

So, Om’s age is 6 and Lalita’s age is 24.

Therefore, after 6 years Lalita’s will be 30 and Om will be 12. Lalita will be 2.5 times elder.

### Question 4 :

**Present ages of Shikhar and Hardik’s are in the ratio of 3:4. The ratio of Bhuvan’s age after 5 years to Hardik’s age 1 year ago is 4 : 3 and four times the difference in ages of Hardik and Shikhar is one more than the age of Bhuvan. Find the average of the present ages of Shikhar and Hardik.**

A. 20 years

B. 10 years

C. 14 years

D. 15 years

Answer:

Correct Option: C

Let Shikhar’s age = A, Bhuvan’s age = B, and Hardik’s age = C

Then, according to the question,

⇒ A/C = 3/4 …………….(i)

⇒ B + 5/ C-1 = 4/3 …………….(iI)

⇒ 4 × (C – A) = B + 1 ——————(iii)

After solving these equations,

⇒ A = 12

⇒ C = 16

Average of ages of Shikhar and Hardik = 12 + 16 / 2 = 14

### Question 5 :

**Vidyut Jamwal was three times Tiger’s age ten years ago, but he will be only twice as old in ten years. What is Vidyut’s present age?**

A. 60 years

B. 70 years

C. 80 years

D. 90 years

Answer : 70 years

Explanation :

Let Vidyut’s present age be “x” years and Tiger’s present age be “y” years.

Then, according to the first condition,

X−10 = 3(y−10) => x−3y = −20………….(1)

Now, Vidyut’s age after 10 years = (x+10)(x+10) years.

Tiger’s age after 10 years = (y+10)(y+10) years.

(x+10) = 2(y+10) => x−2y = 10……(2)

Solving (1) and (2),

we get x = 70 and y = 30

Vidyut’s present age = 70 years and Tiger’s present age = 30 years.
