This math riddle is easy to misread because “divided by half” does not mean divided by two.
Half is written as 1/2, so the problem becomes:
500 ÷ 1/2 + 50
Dividing by a fraction means multiplying by its reciprocal:
500 × 2 = 1,000
Then add 50:
1,000 + 50 = 1,050
The correct answer is 1,050.
Many people answer 300 because they divide 500 by two instead of dividing it by one-half.
