The average age of Ali,Ben and Chandra is 10 years.Ali is 3 years older than Ben.Ben is 6 years older than Chandra.how old is Chandra

Chandra ---- x years

Ben's age ---- x+6 yrs
Ali's age ---- x+6 + 3 = x+9 yrs

(x + x+6 + x+9)/3 = 10

solve for x, then back-sustitute.

To find out how old Chandra is, we need to analyze the given information. Let's break it down step by step:

1. We are given that the average age of Ali, Ben, and Chandra is 10 years. This means that if we add their ages together and divide by 3, we will get 10.
Average age = (Ali's age + Ben's age + Chandra's age) / 3 = 10

2. We are told that Ali is 3 years older than Ben.
Ali's age = Ben's age + 3

3. We are also told that Ben is 6 years older than Chandra.
Ben's age = Chandra's age + 6

Now, let's substitute these equations into the average age equation and solve for Chandra's age:

(Chandra's age + 3 + Chandra's age + 6 + Chandra's age) / 3 = 10

Simplifying the equation:

(3 + Chandra's age + 6 + Chandra's age + Chandra's age) / 3 = 10
(3 + 3Chandra's age + 6) / 3 = 10
(9 + 3Chandra's age) / 3 = 10
9 + 3Chandra's age = 30
3Chandra's age = 30 - 9
3Chandra's age = 21
Chandra's age = 21 / 3
Chandra's age = 7

So, Chandra is 7 years old.
