Logical games: If '-' means'+', '+' means '-', '*' means '÷' and '÷' means '*' then which of the following will be the correct equation?

Correct answer: D. 30 * 5 - 4 + 10 - 15 = 15

  • A. 30 + 5 + 14 - 10 * 15 = 122
  • B. 10 + 5 - 14 + 10 * 15 = 158
  • C. 30 - 5 + 14 + 10 * 15 = 162
  • D. 30 * 5 - 4 + 10 - 15 = 15
