Answer 2

Given,

40% of a quantity is 800 km.

To find,

The value of the whole quantity.

Solution,

The value of the whole quantity will be 2000 km.

According to the question,

40% of a quantity is 800 km.

Let's take the whole quantity to be x km.

So,

$\frac{40}{100} \times x = 800$

4x/10 = 800

Using the cross multiplication method,

4x = (10×800)

4x = 8000

x = 8000/4

x = 2000 km

Hence, the value of the whole quantity is 2000 km.
