Answer:
A new compiler application run 9.9 sec faster than other compiler.
Explanation:
Java runs 15 seconds on a desktop processor
new Java compiler is released that requires only 60 percent = 60/100 =0.6
CPI increase by 10 means 1.1
by applying formula
where
Time pf processor * java compiler release *CPI = fastest compiler
15×0.6×1.1 = 9.9 sec
A new compiler application run 9.9 sec faster than other compiler.
