**Q1. The average age of the mother and her three children is 19. The average age reduced to 10 years if the age of mother is excluded. How old is mother?**

(a) 32 years

(b) 40 years

(c) 38 years

(d) 42 years

(e) 46 years

Ans- Average of mother and her three children=π π’π ππ πππ ππ πππ‘βππ πππ βππ 3 πβππππππ/4

Sum of age of mother and her three children=19Γ 4 = 76 π¦ππππ

Similarly, sum of her three children= 3Γ 10 = 30 years

Mother ageβs=76-30=46years

**Q2. Twenty years ago, the age of father and his son in the ratio of 8:3. Presently, the father is only 127th times of his son then find out the present age of son?**

(a) 28 years

(b) 32 years

(c) 35 years

(d) 21 years

(e) none of these

Ans- Let the present age of son =7π₯

Then the present age of father=12/7Γ 7π₯=12π₯

ATQ,

12π₯β20/7π₯β20=83

π₯ = 5

Present age of son =7π₯=7Γ 5 = 35 π¦ππππ

**Q3. The present age of A and B in the ratio 7:12. 20 years ago, the age difference between Aand B was 15 years. Then find out the sum of present ages of A and B?**

(a) 57 years

(b) 53 years

(c) 76 years

(d) 38 years

(e) 45 years

S3. Ans (a)

Sol.Let present age of A =7π₯ years

And present age of B =12π₯ years

Age difference always remains same

ATQ,

12π₯ β 7π₯ = 15

π₯ = 3

So, sum of present age of A and B =7π₯ + 12π₯ = 19π₯ = 19 Γ 3 = 57 years

**Q4. 8 years ago, the ratio of the ages of Rachana and Archana was 4 : 3. If the ratio of their present ages is 6 : 5 respectively, what is the ratio of the sum and difference of their present ages?**

(a) 11 : 2

(b) 11 : 4

(c) 11 : 1

(d) 11 : 3

(e) None of these

Sol. Rachanaβ²s age/Archanaβ²s age=6x/5x

8 years ago the ratio of their age =4/3

6π₯β8/5π₯β8=4/3

20π₯ β 32 = 18π₯ β 24

2π₯ = 8

π₯ = 4

Rachanaβs age = 24 years

Archanaβs age = 20 years

Required ratio = 44/4=11/1
