I just wrote this code, is there a simplified way?

Question

Calculating simple interest

Answer 1

Ejeh Joseph ,

nice code! just some comments from me:

▪︎before asking the first input, all input options should be shown:

Options:
- Simple Interest (si)
- Principal (pr)
- Time (ti)
- Rate (ra)

What do you want to calculate? -

▪︎there are only 4 inputs needed for the calculation, but each of them occurs multiple times as a code line. try to find a way without this duplicating.

happy coding and good success!

Answer 2

It's a simple equation. Do you know how to make a variable say x as the subject of the equation?

Answer 3

Allan 🔥STORMER🔥🔥🔥🔥 your code will also work fine here. But you need to provide input together line by line like
1000
10
2

It will output 200.00

Answer 4

Ejeh Joseph Your Highness, I will do the needful when I get the Time 😉

Answer 5

Try running this on computer, doesn't work well on sololearn app

Answer 6

Thanks Lothar

Answer 7

Ejeh Joseph there is no built in function in python to get SI directly as per my knowledge...but you can do less code to minimise your input and output part....like you can take all 3 inputs in once
P,R,T = map(int, input().split())
Formula part and then output
result = (P*R*T)/100
print(result)

Answer 8

Ejeh Joseph what do you mean by unknown ...to get a SI you need to provide all three values P and R and T... either by giving constant values or take user input

Answer 9

IMHO you can do this much faster by either :

1 Using functions in Python
2 Using client side JavaScript with alerts 📢 in an HTML page....

Answer 10

Sanjay Kamath can you write the code in Python please

Answer 11

Allan 🔥STORMER🔥🔥🔥🔥 review my code again and see....it can also find the principal, time and rate

Answer 12

Allan 🔥STORMER🔥🔥🔥🔥 yes

Answer 13

Do this,

Since SI=(P*T*R) /100

Then make P the subject by cross multiplying like this

SI*100= P*T*R

Then divide both sides by T*R

You will get

P =( SI*100)/(T*R)

Where P=Principle
SI= Simple Interest
T= Time
R= Rate

Answer 14

Allan 🔥STORMER🔥🔥🔥🔥 change of subject formula is not the problem... my question is if there is a simplified way of writing the code

Answer 15

sudhir meena thanks, but if I have SI, P, R and T is unknown... how to I do that... that's what I built!!... thanks once again

Answer 16

sudhir meena yes I know that. My question is what if you are given the simple, the principal, the rate and you are ask to find the time

Answer 17

Just a comment, the user don't know its the code for SI, so if you list all the options that if calculates, then user can give the right input except user want to calculate anything like add two numbers, anything like that.

Answer 18

Rojan Shrestha thanks I got that

Answer 19

Sanjay Kamath 😂😂 your highness?? Really?? ....

Answer 20

Can any one send me exact concepts of core java That are used in Intrview???
