Answer 2

Answer:

The difference of the number is 50.

Step-by-step explanation:

Two number are in the ratio 5:7. Let the two numbers are 5x and 7x.

Diminishing each of them by 40 they become in the ratio 17:27.

$\frac{5x-40}{7x-40}=\frac{17}{27}$

$27(5x-40)=17(7x-40)$

$135x-1080=119x-680$

$16x=400$

$x=25$

The value of x is 25. So, the two numbers are

$5x=5\times 25=125$

$7x=7\times 25=175$

The difference of the number is

$175-125=50$

Therefore the difference of the number is 50.
