Question

Sam started a new business with an investment of Rs.1, 00,000. During the first year the he got a profit of x%, whereas in the second year he lost a certain amount(say Rs. Y). Help him to find out the profit/loss (in terms of initial investment) in percentage at the end of the second year.

Answer 1

Answer:

The loss% at the end of second year is $\dfrac{y - ( 1,00,000 + x)}{y}$  

Step-by-step explanation:

Given as :

The initial investment amount = Rs 1,00,000

The profit percentage in first year  = x %

So, Amount in first year = investment amount + x% of investment amount

Or, Amount after first year = Rs 1,00,000 + $\dfrac{x}{100}$ × Rs 1,00,000

∴ Amount after first year = Rs 1,00,000 + Rs 1000 x

i.e Amount after first year = Rs ( 1,00,000 + 1000 x )

Again

In second year, The loss amount = Rs y

So, loss % after second year = $\dfrac{y - ( 1,00,000 + x)}{y}$  × 100

Or, loss % = $\dfrac{y - ( 1,00,000 + x)}{y}$

Hence, The loss% at the end of second year is $\dfrac{y - ( 1,00,000 + x)}{y}$  Answer

Find Profit or Loss Program in Java

Sam started a new business with an investment of Rs.1, 00,000. During the first year the he got a profit of x%, whereas in the second year he lost a certain amount(say Rs. Y). Help him to find out the profit/loss (in terms of initial investment) in percentage at the end of the second year.

Sample input 1:

Enter the profit percentage

20

Enter the amount lost in Rs.

50000

Sample output 1:

After two years he gets a loss of 30%.

Explanation :

investment = 100000

profit = 20% of 100000 = 20000

Loss=50000

If loss > profit, there is a loss

If loss < profit, there is a profit

If loss = profit, no gain no loss

Here loss > profit So loss

To calculate  loss% -  

loss amount = loss - profit = 30000

Loss % =( loss amount  / investment)    * 100              

That is 30000 * 100 / 100000 = 30%

Sample input 2:

Enter the profit percentage

20

Enter the amount lost in Rs.

20000

Sample output 2:

After two years he gets no loss or no gain.
