A glass is

Marrrta [24]

total volume of the glass is $}x =200cm^3$ .

<u>Step-by-step explanation:</u>

Here we have , A glass is 1/4 full. Then 70cm3 of orange juice is poured in.

The glass is now 3/5 full. We need to find that What is the total volume of the glass . Let's find out :

Suppose that volume of glass is x ,so according to question we have the following equation

$\frac{x}{4}+70 = \frac{3x}{5}$ , Now, solve this to find value of x

⇒ $\frac{x}{4}+70 = \frac{3x}{5}$

⇒ $70 = \frac{3x}{5}- \frac{x}{4}$

⇒ $70 = \frac{3x((4)-x(5)}{5(4)}$

⇒ $70 = \frac{12x-5x}{20}$

⇒ $70(20) = 12x-5x$

⇒ $7x = 1400$

⇒ $\frac{7}{7}x = \frac{1400}{7}$

⇒ $}x =200cm^3$

Therefore, total volume of the glass is $}x =200cm^3$ .
