The average of two 3-digit numbers is 380. The first two digits of the first number are as shown. What is the smallest possible value for the second number?

The sum of the two numbers is 380 × 2 = 760.

To get the smallest possible value for the second number, the first number should be made the largest possible value: 239.

Therefore, the smallest possible value for the second number is 760 – 239 = 521.
