Answer 2

Question :-

40% of a number is 500 km. Find the whole quantity.

Now,

Let the unknown quantity be '$x$'

Thus,

40% of $x$ is 500 km.

$\frac{40x}{100} =500$

$=>40x=500$ × $100$

$=>40x=50000$

$=>x=50000\div40$

$=>x=1250$

Verification :-

LHS = $40$% of $x$

= $\frac{40}{100}$ × $1250$

= $\frac{40}{10}$ × $125$

= $4$ × $125$

= $500$

RHS = $500$

LHS = RHS hence, verified.

Hence,

The value of the unknown quantity ($x$) is 1250 km.
