__Age Aptitude Tricks__

__Type 1:__**1) The ratio of Asha and Sushma are in ratio 3:4 after 8 year the ratio of their ages will be 7:8. What is difference in years between their ages?**

**Solution:**

8 years × (difference 8-7) / (7×4) – (8×3)

= 8 × 1 / 28-24

Difference =8/4 = 2

**2) 10 years ago ratio of ages of A and B was 3 : 1 and after 10 years the ratio of their ages become 2 : 1. Find the sum of present ages?**

**Solution:**

Given total years 10 and 10 so we take 20 years

20×1 / 1 = 20

A B

10 years ago 3×20 : 1 × 20

Present age 60+10 : 20+10

Sum = 100 years

**3) 5 years ago ratio of age A and B are 5 : 9 and after 5 years it will become 5 :8 find present age?**

__Type 2:__**1). Ratio between the ages of Mother (M) and her Daughter (D) 4 years ago was 19 : 5. If difference between ages of mother and daughter is 28 years what will be the ratio of their present age?**

**2). 3 years ago A was 4 times as old as B. After 18 years A age will exceed B’s age by 12 years. The ratio of present ages of A and B is?**

**3). Divya got married 6 years ago. Today her age is 1 ¼ times her age at the time of marriage. His son age is 1/10 times her age. Age of her son is.**

**(T) – Today Present Age Ratio**

__Type 3:__**1). Five years ago the sum of the ages of Father and Son was 60 years. The ratio of present ages is 4 : 1. What is the present age of father?**

**Solution**:

Present age of F + S = 60 + 10 = 70

F : S

4 : 1 ( present age)

5 –> 70

1 –> 14

Present age of F = 14 × 4 = 56 years

__Type 4:__**1). Sum of ages of father and son is 46 years. Seven years ago the product of their ages was 4 times the father age at that time. Find present age of father and son?**

**Solution:**

(F-7) ×(S-7) = 4 × (F –7)

S – 7=4

S = 11 years (present)

F = 35 years (present)

__Type 5:__**1). Ratio of Arjun and Bhuvan age is 3 : 5. Ratio of Bhuvan and Cibi is 2 : 3. If Arjun is two fifth of Cibi what is Arjun’s age?**

__Type 6:__**1). The Average of 8 men is increased by 2 years when two of them whose ages are 21 and 23 are replaced by Two new men. The average of two new men is?**

**Solution**:

Thus in numerator there must be changed of 16 to change average age by 2

Increase 2 years = 8 × 2 = 16

Two men = 21 + 23 = 44

= 16 +44 = 60

Average 60/2 = 30 years

**2). The average age of family of 10 members is 20 years. If the age of youngest member of the family is 10 years then the average of the member of family just before the birth of youngest member was approximately?**

**Solution:**

Here number is not constant and notion of time too

Thus total age = 20 × 10 = 200

10 years ago = 200 (10 ×10)

= 200-100

= 100

Average = 100/9
