Question

9 a juice container was 4/5 full. Ravinder poured 4 glasses from it and then poured two glasses back. The container now is 3/4 full. How many glasses can be filled if the entire container is emptied?

Answer 1

40 glasses can be filled if the entire container is emptied.

Explanation

Suppose,  $x$ number of glasses can be filled if the entire container is emptied.

As the juice container was $\frac{4}{5}$ full, so the number of glasses already in the container $=\frac{4}{5}x$

Ravinder poured 4 glasses from it and then poured 2 glasses back and the container now is $\frac{3}{4}$ full.

So, the number of glasses remaining in the container $=\frac{3}{4}x$

Thus, the equation will be........

$\frac{4}{5}x-4+2 =\frac{3}{4}x\\ \\ \frac{4}{5}x-2 =\frac{3}{4}x \\ \\ 20(\frac{4}{5}x-2) =20(\frac{3}{4}x)\\ \\ 16x-40=15x\\ \\ 16x-15x=40\\ \\ x=40$

So, 40 glasses can be filled if the entire container is emptied.
