The value of AX will be 30, and the no. of times the loop will run is 5 times.
Explanation:
The loop instruction will decrements cx and jump to label if cx is not equal to zero.
As cx is set to 5, the loop will decrement cx 5 times to become 0, hence the loop will run 5 times.
Also in the Loop the register BX is increamented and Added to AX, hence AX value after 5 loops will be
AX = 4+5+6+7+8 = 30
