The "Binocular bottle kids puzzle" is a very famous puzzle among kids. Below is the solution for it.
2nd row:
4 bottles + 4 bottles + 3 bottles = 33
11 bottles = 33
1 bottle = 33 ÷ 11
1 bottle = 3
3rd row:
2 binoculars + 1 binoculars + 1 binoculars = 24
4 binoculars = 24
1 binoculars = 24 ÷ 4
1 binoculars = 6
1st row:
(2 people + 2 bottles + 1 binoculars) + (2 people + 1 bottle) + (2 people + 1 bottle + 1 binoculars) = 30
Sub 1 bottle = 3 and 1 binoculars = 6
(people + 2 x 3 + 1 x 6) + (2 people + 1 x 3) + (2 people + 1 x3 + 1 x 6) = 30
(2 people + 6 + 6) + (2 people + 3) + (2 people + 3 + 6) = 30
2 people + 12 + 2 people + 3 + 2 people + 9 = 30
6 people + 24 = 30
6 people = 6
1 people = 6 ÷ 6
1 people = 1
2 people (a boy and a girl ) = 2
4th row:
1 bottle + 2 binoculars x (2 people + 2 bottles + 1 binoculars)
= 3 + (2 x 6) x (2 + 2 x 3 + 6)
= 3 + 12 x ( 2 + 6 + 6)
= 3 + 12 x 14
= 3 + 168
= 171
