This is a cryptarithmetic puzzle. From the units column, A + B ends in 1. From the tens column, B + 8 + (carry) ends in 1. Let's assume a carry of 1 from the units column, so A+B=11. Then for the tens, B+8+1 = 11, which gives B=2. If B=2, then A=9. Let's check: 192 + 82 = 274. This does not equal 211. The problem is likely flawed as stated.
