If $x=2y$ and $4x=48$, then value of $y$ is

We can multiply or divide both the sides of a linear equation by 

Solve:

$\frac{2}{3}\left(5x-2\right)-\left(3x-\frac{3-x}{2}\right)=\frac{1-x}{5}$

Solve:

$\frac{2}{3}\left(4x-1\right)-\left(2x-\frac{1+x}{3}\right)=\frac{1}{3}x+\frac{4}{3}$

An old man gives one-fourth of his property to his son, one-fourth of his property to his daughter and the rest to his wife. His wife gave one-third of her share to the World Wide Fund for Nature (WWF). If the value of the property she gave to the WWF was $₹10,000$. Find the total value of the property and the amount each person got.

Find out what is the contribution of the WWF in protecting animals.
