Answer:
159
Step-by-step explanation:
It's very simple but quite tricky, let's do three simple steps below to solve this puzzle:
Firstly, let's declare the variables:
a = a couple of people
b = a water bottle
c = a binocular
Secondly, let's analyze the image carefully:
- On the top picture we can call it Equation 1 or eq. 1 , we can see the picture summarizing three set of a couple of people (a ): ( 1 ) the first left couple bring a water bottle and binocular, thus we can denote it as summation of abc or ∑(abc). ( 2 ) the second image of couple only bring a water bottle, thus we can denote it as ∑(ab), ( 3 ) the third image of the couple only bring a binocular, we can denote it as ∑(ac).
- The second row of the picture we can call it eq. 2, where the first, second, and third image are 4 water bottles, 4 water bottles, and 3 water bottles, respectively. Thus adding all of them give 33 as a result.
- The third row of the picture we can call it eq. 3, where the first image contains two binocular, and the rest are just a single binocular. The result of this equation is 24.
- The fourth row of the picture we can call it eq. 4 , where: ( 1 ) the first image is just a single water bottle, ( 2 ) the second image contains two binoculars, and ( 3 ) the third image is a couple who bring a water bottle and a binocular. The result of this equation is unknown (we can denote it as X ). NOTE that this fourth row is tricky, we can see the second operation is a multiplication.
With the descriptions above, we can summarize this picture with these four equations:
(eq. 01): ∑(abc) + ∑(ab) + ∑(ac) = 30
(eq. 02): 4b + 4b + 3b = 33
(eq. 03): 2c + c + c = 24
(eq. 04): b + 2c x ∑(abc) = X
Lastly, it's time to do some math:
(eq. 02):
4b + 4b + 3b = 33
11b = 33
b =
b = 3
(eq. 03):
2c + c + c = 24
4c = 24
c =
c = 6
okay now we got the value of b and c, let's find the value of a:
(eq. 01):
∑(abc) + ∑(ab) + ∑(ac) = 30
(a+b+c) + (a+b) + (a+c) = 30
(a+3+6) + (a+3) + (a+6) = 30
a + 9 + a + 3 + a + 6 = 30
3a + 18 = 30
3a = 30 - 18
3a = 12
a =
a = 4
Finally we got all the variables, which are a=4, b=3, and c=6. Now let's calculate the final equation:
(eq. 04):
b + 2c x ∑(abc) = X
3 + 2(6) x (4+3+6) = X
3 + 12 x 13 = X
3 + 156 = X
X = 159
That's it, the unknown result from this puzzle is 159
