Solution

The given ratio is x:y = 3:4.

We need to find the ratio (7x+3y) : (7x-3y).

Substitute x = 3k and y = 4k (where k is a constant) in the above expression.

So, (7x+3y) : (7x-3y) becomes (73k + 34k) : (73k - 34k) = (21k + 12k) : (21k - 12k) = 33k : 9k = 33:9 = 11:3.

So, the correct answer is 11:3.
