ExplanationLet the present ages of Kapil and Avanthi be K & A
Given difference in their ages = K - A = 9 years ...........(1)
After 7 years, K + 7 = 2(A + 7) ......(2)
K + 7 = 2A + 14
K - 2A = 7 ............(3)

-A = -2
=> A = 2 years
=> K = 9 + 2 = 11 years
Required, age of Kapil after 4 years = 11 + 4 = 15 years.

Correct Answer: 18
Explanation:
Given Karthik?s age = 32 years
Karthik?s son age = 7 years
Difference between their ages = K - S = 32 - 7 = 25 years ?.(1)
Now, required K = 2S ??(2)
Put (2) in (1)
2S - S = 25
=> S = 25 years
Hence, at the age of 25 years of Karthik?s son, Karthik will be twice as his son?s age.
25 - 7 = 18 years
Therefore, after 18 years the father be twice as old as the son.

Explanation:
Given the ages of Sunitha and Pranitha are 40 years and 60 years.
Let before 'm' years, their ages be in the ratio of 3 : 5
ATQ,
=> 200 - 5m = 180 - 3m
=>2m = 20
=> m = 10 years.
Correct Answer: 8, 72 yrs
Explanation:
Let the present ages be K,M
Given K/M = 4/5
5K - 4M = 0 ......(1)
Also given that,
M - (K + 5) = 3
M - K = 8 .........(2)
Then, by solving (1) & (2)
M = 40 yrs and K = 32 yrs
Hence, Total of ages = 40 + 32 = 72 yrs
Difference of ages = 40 - 32 = 8 yrs.
Correct Answer: 50 yrs
Explanation:
Let age of retirement = S
so according to the given condition 25000(x-20)
=10000 x 3 + 12000 + 14000 + 16000 + 18000 + 20000 + 22000 + 24000 + 26000 + 28000 + 30000 + 30000(S-33)
= 30000 + 210000 + 30000S-990000
= 30000S - 750000
or 25000S - 500000 = 30000x - 750000
or 5000x = 250000
or S = 50 yrs.
Correct Answer: 18 years
Explanation:
At the time of marriage, let Sudeer's age be 4x, then Swetha's age is 3x
12 years after:
Age of Sudeer = 4x+12
Age of Swetha = 3x+12
Now the equation is 3x+12=5/6(4x+12)
Solving equation we get x=6
Hence Swetha got married at the age of 18.
