One option is to assign a variable and go from there.
The easier/faster approach is to assign a "nice" value for the price of product T, and then go from there.
Let's say product T costs $100
Given: Product S is 30 percent higher than the price of product T
So, the price of product S = $100 + (30% of $100) = $100 + $30 = $130
Given: The price of product R is 20 percent higher than the price of product S
So, the price of product R = $130 + (20% of $130) = $130 + $26 = $156
Question: The price of product R is what percent higher than the price of product T?
In other words, $156 is what percent higher than $100
Here it's clear that, $156 is 56% percent greater than $100

Let the prices be R, S and T resp.
R = 1.2S and S = 1.3T
R = 1.2(1.3T)
R = 1.56T
Hence, option B
You can also assume some numbers
Let T = 100
then, S = 130 and R = 156
