Answer : (1) 3 : 1
Explanation:-
x/y = 3/4
Then, x = 3 and y = 4
Put the value of x and y in the given equation,
Then,2x + 3y and 3x – 2 y
=  2 x 3 + 3 x 4 and 4 x 3 – 2 x 3
= 6 + 12 and 12 – 6
= 18 and 6
Then, the ratio of (2x + 3y) and (3y – 2x) = 18/6
= 3/1
= 3 :1
Hence, the answer is (1) 3 : 1.
