Using algebra
Let t be a unit of ties and s be a unit of shirts
2t=3s
4t=6s
4s+4t=120
4s+6s=120
10s=120
1s=120/10=12

cost of 4 ties will be the same as 6 shirts.
10 shorts will be $120
1 shirt will be $12

EQ1: 4S + 4T = 120
EQ2: 3S -2T = 0
EQ3= EQ2*2: 6S – 4T = 0
EQ4 = EQ3 + EQ1: 10S = 120
S = 12

Just to offer pictorial solving if algebra is a little challenge for P4 kids. Can also view as a bridging tool to guide from the familiar model/pictorial presentation to algebra solving.
Personally, I faced some resistance from my child to use try to learn another method when he gets familiar (or too familiar) to one method. Then I would use chances like this to ask how he will feel if he needs to draw 10 buckets… to get the idea that it is only to one’s advantage to learn different kinds of methods and use whichever one that comes in handy.
