Given that the sum of ages of amit, bhanu and Chandra is 27.
Then, According to the given information,
x +2x +2x +2 = 27
5x +2 =27
5x = 27-2
5x = 25
x =25/5
x =5
___________
Bhanu's age is 2x = 2×x =2×5 =10

The age of Bhanu is 10 years.
Given:
The age of Amit is two greater than that of Bhanu and Bhanu is twice as old as Chandra.
To Find:
The age of Bhanu =?
Solution:
Here, we will express the condition expressed in the problem in mathematical form as follows;
Let us assume the age of Amit is 'a', the age of Bhanu is 'b', and the age of Chandra is 'c'.
Now, according to the given conditions;
a = (b + 2) ----------------- (2)
b = 2c ----------------- (1)
Substituting (2) in (1), we get;
∴ a = (2c + 2) ------------------- (3)
Now, We have given that the total of their ages is equal to 27.
i.e., a + b + c = 27
⇒ (2c + 2) + 2c + c = 27 ------------------ From (1), (2), and (3)
⇒ 5c + 2 = 27
⇒ 5c = 27 - 2
⇒ 5c = 25
⇒ c = 5
Thus, the age of Amit is (2c + 2) = 12 years.
The age of Bhanu is 2c = 10 years.
The age of Chandra is c = 5 years.
Therefore, Bhanu is 10 years old.
