Average of three positive numbers is 25. Out of these three numbers, the average of two numbers is 11. Which is the smallest number?

**(A)** 3

**(B)** 4

**(C)** 5

**(D)** Data is not sufficient to find the smallest number

**(E)** None of the above

Let three positive numbers be and .

## It is given to us that

**(1)**

## It is also given to us that

** (2)**

Putting equation **(2)** in equation **(1)**, we get

We cannot find any other number using the present data. Hence, we cannot say which one is the smallest.

Hence, the answer is **(D)**.
