Answer:
The ratio of their ages 10 years ago is 1:23:56.
Step-by-step explanation:
Given:
- Rajeev's present age is 100/3% of his father's age.
- And His father's age is half of Rajeev's grandfather's age.
- The average of the present ages of all of them is 100/3. Years.
To find:
- The ratio of their ages 10 years ago?
Required Solution:
Let Rajeev's present age = x
His father's present age = 3x
Now grandfather's present age = 6x
Then equation is:-
Hence,
Rajeev's present age = x = 11 years
So,
10 years ago Rajeev's age = 11 – 10
= 1 years
His Father's present age = 3x = 3×11
= 33 years
10 years ago father's age = 33 – 10
= 23 years
Grandfather's present age= 6x = 6 × 11
= 66 years
10 years ago = 66 – 10 = 56 years
Therefore,
Required Ratio = 1:23:56
The ratio of their ages 10 years ago is 1:23:56.
