Prashant bought a device from an online store for Rs. 22000, but it was faulty so he returned it, the company accepts a return after deducting 10%. He saw the same device at a discounted price of Rs. 19000, he again ordered the same device, again it was found faulty, he makes a return, the company takes the return after deducting 12%. The amount of money he lost in this whole transaction is what percent of the cost of the device he bought initially?

On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
