Three identicalsized barrels are shown below If the contents

Three identical-sized barrels are shown below. If the contents of two of the barrels are poured into an empty third barrel will be filled? As an aid in drawing the human body, artists divide the body into three parts. Each part is then expressed as a fraction of the total body height. For example, the torso is 4/15 of the body height. What fraction of body height is the head?

Solution

first conatiner is 3/4 full and the third container is 1/4 full so when we empty the containers in the middle , it will be completely filled as

3/4 +1/4 = 1

2)

we are given that

below waist = 3/5 and torso = 4/15

so head fraction can be calculated as

1 - (3/5 + 4/15) =

1- (13/15)

= 2/15
