Sum of age of mother and her three children=19Γ— 4 = 76 π‘¦π‘’π‘Žπ‘Ÿπ‘ 
Similarly, sum of her three children= 3Γ— 10 = 30 years
Mother age’s=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

(e) none of these

Ans- Let the present age of son =7π‘₯
Then the present age of father=12/7Γ— 7π‘₯=12π‘₯
ATQ,
12π‘₯βˆ’20/7π‘₯βˆ’20=83
π‘₯ = 5
Present age of son =7π‘₯=7Γ— 5 = 35 π‘¦π‘’π‘Žπ‘Ÿπ‘ 

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?

And present age of B =12π‘₯ years
Age difference always remains same
ATQ,
12π‘₯ βˆ’ 7π‘₯ = 15
π‘₯ = 3
So, sum of present age of A and B =7π‘₯ + 12π‘₯ = 19π‘₯ = 19 Γ— 3 = 57 years

6π‘₯βˆ’8/5π‘₯βˆ’8=4/3
20π‘₯ βˆ’ 32 = 18π‘₯ βˆ’ 24
2π‘₯ = 8
