In the photo attachment, there are 4 pictures of scales. In each scale, there are a number of marbles weighed with 4 different types of objects. The number of marbles weighed varies for each object.
The marbles are weighed by cars: 5 items
Marbles are weighed with rubber ducks: 3 items
The marbles are weighed with monkey dolls: 6 items
Marbles weighed with robots: 4 items
The number of marbles is used to find out which object is the lightest
Because 10 is less than 11 (10 <11), the lightest object is a doll + robot
Because the total marbles are equal 9, then there are no objects that are lighter or heavy (both objects are balanced in weight)
Because 8 is less than 10 (8 <10), the lightest object is a car + rubber duck
Because 7 is less than 11 (7 <11), the lightest object is a rubber duck + robot
