# Calculator Riddle

# SOLUTION:

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.

**So the answer is 333.**
