If h:k = 2:5, x:y=3:4 and 2h+x:k+2y = 1:2, find the ratio h-x: k-y.​

Given:

To find:

Solution:

We have, and .

Let the values of h and k are 2a and 5a respectively.

Let the values of x and y are 3b and 4b respectively.

We have,

It can be written as

On further simplification, we get

Now,

On further simplification, we get

Therefore, the ratio is .

number one is the correct answer
