Question

A glass is 1/4 full. Then 70cm3 of orange juice is poured in. The glass is now 3/5 full. What is the total volume of the glass?

Answer 1

A glass is 1 4 full. Then 70cm3 of orange juice is poured in. The glass is now 3 5 full.

Given,

Let the total volume of the glass  = x cm³

70 cm³ of orange juice was poured in the glass.

A glass was 1/4 full before the mixing of orange juice

The glass was 3/5 full after the mixing of orange juice

The volume of glass is  

(3/5 - 1/4) × x = 70

[ ( 12 - 5 ) / 20 ] × x = 70

7 × x = 70

x = 10 cm³

Therefore, the total volume of the glass is 10 cm³
