This math puzzle is really interesting and is viral all around the world. This tricky math question is one of the most shared images in WhatsApp during the 2020 lockdown period.

We have solved this and given a solution with the explanation below. Share if you like.

__ANSWER__

**405 is the answer**

__Explanation__

**Equation 1**: 9 + 9 + 3 = 21 (In this eqn, First & Secong Clock time is 9 o'clock & time in third clock is 3 o'clock)

**Equation 2**: 10 + 10 + 10 = 30 (In this eqn, Calculator = 10 ; Also note that the sum of the values entyered in the calculator is also 10

**Equation 3**: 15 + 15 - 15 = 15 (In this eqn, Bulb = 15 ; Also note that we get 15 by multipliying the number of rings at the bottom of the bulb and number of lines shown above the bulb (3 x 5).

**Equation 4: 9 + 9 x (12 + 16 + 16)**

**=> 9 + 9 x 44**

**=> 9 + 396**

**=> 405**(In this eqn, The time in clock = 9 ; The sum of the values entered in the calculator is 9 ; To get the values of each bulb, multiply the rings and the lines above the bulb)

ReplyDeleteit should be 333

ReplyDeleteI agree with you

DeleteDid you look at the bottom lightbulbs? They all have different amount of rings!

Deletethe correct answer is 333.

ReplyDelete9+(9*(12+12+12))=333

Correct answer

DeleteWrong, the answer is 9

DeleteTe correct answer ia 334. 9 + 9 x (12 + 12 + 12)

ReplyDelete333

DeleteCorrect1 For me!

DeleteIn equation 4, one of the bulbs has fewer screws

ReplyDeleteCorrect answer is 333

ReplyDeleteThe answer is 405 as described in the answer above. The bulbs in the final equation, one has 3 rings at the bottom, the other two have 4 rings. Multiply the number of rings with the 4 lines above the bulb to get its value. So 3x4=12, 4x4=16, 4x4=16. Total is 44.

ReplyDeleteEquation 4: 9 + 9 x (12 + 16 + 16)

=> 9 + 9 x 44

=> 9 + 396

=> 405

Correct, I agree

DeleteWhat about the lumens on top?

DeleteThe answer is 9.

ReplyDeleteThe calculators in row 2 show "1234", however the one in the last row shows "1224", 10 less.

ReplyDelete1.9 + 9 + 3 = 21

ReplyDelete2. 10 +10 +10 =30

3. 2 bulb - 1bulb = 15

bulb with 5 lights = 15 ( light means see upper lines on the bulb)

bulb with 1 light = 3

4. clock = 9

calculator = 1+2+2+4 = 9

bulb with 4 light = 3 x 4 = 12

3 bulbs with four light = 12×3 =36

sum = 9 + 9 ×36 = 9 + 324 = 333

Wrobg, the answer is 9

Delete405 is not correct answer. 1450953 is the correct answer. 9+(9*161216)=1450953. In equation 4 there are no pluses, minuses etc. between the bulbs. So the obvious way to look at that number is 161216, them multiply that with the calculator (9) and add the clock (9). Why would it make sense to add a plus sign between the bulbs when there are no plus signs. Plus signs are already where they are supposed to be ;)

ReplyDeleteThere is also a SECOND correct answer. 1+2+3+4=10 AND (1x2x3)+4=10 In that scenario the answer is 361. 405 AND 361 are correct. :)
