Question

A glass is 1/3 full. Then 75cm3 of orange juice is poured in.The glass is now 3/4 full. What is the total volume of the glass?

Answer 1

Answer:

let total capacity of glass be y.

Then

(1/3)y +75 = (3/4)y

75 = (3/4)y - (1/3)y

75 = (5/12)y

75*12 = 5y

y =180

Hence total volume of glass

$180 {cm}^{3}$
