Q10 What is Aman's present age, if after 20 years his age will be 10 times his age 10 years back?
1. Answer - B Explanation
If the age of Mr.
Ram 5x and 4x is the age of Mr.
Then, (5x + 3) /( 4x+3) = 11/9
⇒ 9 (5x+3) = 11 (4x+3)
⇒ x= (33-27) = 6
So the present age of Mr.
sham = 6*4 = 24 years.
Answer - A Explanation
Let daughter present age be x year .
in that case mother present age would be = 30x years
30x + 18 = 3 (x+ 18)
⇒ 27x = 36
⇒ x = 4/3
∴ so the present age of mother = (30* 4/3) = 40 years.
Answer - A Explanation
If the present age of ajay , vijay and sanjay is 4x , 7x and 9x years.
Total sum of ages of ajay, vijay and sanjay before 8 years ago = (4x-8)+(7x-8)+(9x-8)
∴ 20x-24 = 56 ⇒ 20x = 80 ⇒ x= 4
Hence, it proves that age of ajay is 4*4 = 16 years,
vijay (7*4) = 28 years and sanjay (9* 4) = 36 years.
Answer - B Explanation
If the present age of mother is equal to x year.
In that situation the daughter present age would be = 2x/5 years.
2x/5 + 8 = 1/2 (x+8) ⇒ 4x+ 80 = 5x+40 ⇒ x = 40.
The mother age at the present time is = 40 years.
Answer - C Explanation
Before 3 year let bhuvan age be x years.
3 years before , ajay age will be 2x years.
Now Bhuwan's age =(x+3) years and ajay age = (2x+3) years.
Ratio of the ages of man and son after 10 years = (65+10)/(35+10)= 75/45 = 5/3
Sol : Option C
Let the daughter's age be x and father's age be 4x.
So as per question, 4x + 5 = 3(x + 5).
So x = 10.
Hence present age of daughter is 10 years and present age of father is 40 years.
So after 5 + 5 = 10 years, daughter age would be 20 years and father’s age would be 50 years.
Hence father would be 50/20 = 2.5 times of daughter’s age.
Sol : Option C
Let Aman's present age be x
Aman's age before 10 years = x - 10)
Aman's age after 20 years = (x + 20)
We are given that, Aman's age after 20 years (x + 20) is 10 times his age 10 years back (x – 10)
Therefore, (x + 20) = 10 (x – 10)
Solving the equation, we get x + 20 = 10x – 100
9x = 120, x = 13.3 years
