Where do charts get the data series names?

For an external usb hard drive attached to a computer, which is more suitable: a writethrough cache or a block cache

Charra [1.4K]

Disk access is way slower than memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which reduces disk accesses time. Here a portion of disk is bought to cache for reading and a modified blocks are first changed in cache but reflected in the disk at one go. On the other hand with write through caching each modified block is written to cache and at the same time it is written to the disk. Write- through caching requires more disk I/O so they can have a negative effect on the performance.

A cycle merchant allows 15% discount on the marked price of a bicycle and still he makes a profit

lions [1.4K]

Answer:

The program in Java is as follows:

public class Main{

public static void main(String[] args) {

double discount_percent = 0.15;

double discount_amount = 600;

double profit = 0.20;

double marked_price = discount_amount/discount_percent;

double cost_price = marked_price/(1 + profit);

System.out.println("Marked Price: "+marked_price);

System.out.println("Cost Price: "+cost_price);

}}

Explanation:

For explanation purpose, let

$MP \to$ Marked Price

$\%D \to$ Percentage discount

$D \to$ Discounted amount

$\%P \to$ Percentage Profit

$C \to$ Cost Price

The marked price (i.e. selling price) is calculated discount using:

$MP = \frac{D}{\%D}$

The derived formula of the cost price from percentage profit and Marked Price is:

$C = \frac{M}{1 + \%P * 100}$

So, the explanation is as follows:

The next three lines declare and initialize the given parameters

double discount_percent = 0.15;

double discount_amount = 600;

double profit = 0.20;

Calculate marked price

double marked_price = discount_amount/discount_percent;

Calculate cost price

double cost_price = marked_price/(1 + profit);

Print marked price

System.out.println("Marked Price: "+marked_price);

Print Cost price

System.out.println("Cost Price: "+cost_price);
