Question

The difference between a number and its two fifth is 510 what is10 percemt of thst number

Answer 1

Answer:

85.

Step-by-step explanation:

Let the number be x.

So, from the language given,

$x - \frac{2}{5} x = 510$

Or, $\frac{3}{5} x = 510$

Or, $x = \frac{5}{3} * 510$

So, $x = 850$

Now, we're asked 10% of the number, that is, 10% of x.

So, required quantity = $\frac{10}{100} * x$ = $\frac{1}{10} * 850 = 85$

The required quantity is 85.
