@Snehal and @Sujata.

@Muneer.
= 25000 * (1+12/100) => 250009112/100)^3.
= 25000(56/50)^3.
= 25000(28/25)^3.
And now expand the cube root we get 25000 * 28/25 * 28/25 * 28/25.
= 25000 * (1+12/100) => 250009112/100)^3.
= 25000(56/50)^3.
= 25000(28/25)^3.
And now expand the cube root we get 25000 * 28/25 * 28/25 * 28/25.
