There are three numbers A, B, and C. If A is reduced by 5 and B is increased by 5, then their values become equal. If C is increased by 10 and B is increased by 10, then their values become equal. If the sum of A and C is 450, then find the value of B.

1. 330
2. 220
3. 440
4. 110

Correct answer: 220

Solution

From A - 5 = B + 5, we get A = B + 10. From C + 10 = B + 10, we get C = B. Now A + C = 450 gives (B + 10) + B = 450, so 2B = 440 and B = 220.
