We need to find 2 values in the graph, x and a value 1.5*x.
To figure this out faster, we should realize that x must be an even number so that 1.5x is a whole number, since an odd number multiplied by 1.5 would result in a number with decimals.
Only 2 values fit this, Donizetti with 10 and Verdi at 14.
10*1.5 = 15 and 14*1.5 = 21. Since there is no value with 21 in the graph, it must be 10. Hence the answer is Donizetti at 10 and Puccini at 15.
