Find the value of one clock using the first equation. According to first equation, 9’o clock + 9’o clock + 3’o clock = 9 + 9 + 3 = 21. Therefore; 1 Clock = 1 Using equation two, three calculators are equal to 30. Therefore, one calculator is equal to 10. Also, the sum of numbers inside the calculator is 1 + 2 + 3 + 4 = 10.
Therefore, the value of the calculator depends on the sum of the numbers inside it. According to equation three, 1 Bulb + 1 Bulb – 1 Bulb = 15. Cancelling out the + and -; we get 1 Bulb with five lights = 15, Therefore, one bulb with one light = 3. Bulb with four lights = 4 x 3 = 12. The final equation is – 9’o clock + Calculator (1+2+2+4) x 3 bulbs (with four light rays each) Translating the final equation into numbers – 9 + (1+2+2+4) x 3(12), 9 + 9 x 36 = 9 + 324 = 333.
