(y - x)
If 1.5x = 0.04y, then the value of
(y + x)
is​

Answer 1

Step-by-step explanation:

Correct Question:-

If 1.5x = 0.04y, then the value of (y-x)/(y+x) ?

Given:-

1.5x = 0.04y

To find:-

Find the value of (y+x)?

Solution:-

Given that:

1.5x = 0.04y

=> (15/10)x = (4/100)y

=> (3/2) x = (1/25)y

=> 3x/2 = y/25

On applying cross multiplication then

=> 25×3x = 2×y

=> 75x = 2y

=> 75x /y = 2

=> x/y = 2/75

We know that

a:b can be written as a/b

=>x : y = 2 : 75

Let x = 2k

Let y = 75k

Now,

y-x = 75k-2k = 73k

y+x = 75k+2k = 77k

The value of (y-x)/(y+x)

=> 73k/77k

=> 73/77

Answer:-

The value of (y-x)/(y+x) for the given problem is 73/77

Used formulae:-

• a:b can be written as a/b
