Two-thirds 2829

If we pour one-fifth and then another 50 liters from the barrel, two-thirds of the original volume will remain in the barrel. What is the volume of the barrel?

Correct answer:

x =  375 l

Step-by-step explanation:


x-x/5-50=2/3x

x-x/5-50=2/3·x

2x = 750


x = 750/2 = 375

x = 375
