Answer 2

Answer

There will be NO PROFIT or LOSS

Step-by-step explanation:

We will use the following formula to find the Gain Amount,

( $x$ ) + $\frac{y}{100}$  x $x$  

here we have

$x$ = 18,000

$y$ = 20

So the equation will be like :-

$( 18000 ) + \frac{20}{100}$  x  $18000$

= 18000 + (20 x 180)

= 18000 + 3600

= 21600

∴ The Gain amount is Rs 21,600

Let's find the Loss amount by changing the ( + ) sign into ( - ) sign,

So the equation will be like :-

$18000 - \frac{20}{100}$ x $18000$

= 18000 - (20 x 180)

= 18000 - 3600

= 14400

∴ The Loss amount is Rs 14,400

Now,

We will add the Gain amount and the Loss amount

= 21,600 + 14,400

= 36,000

To find the Gain/Loss amount on the whole transaction we will subtract (36,000) from (18,000)(2)

So we will get :-

(36,000) - (36,000)

= 0

As we are getting the difference as 0 we can say that,

The person is getting NO PROFIT or LOSS on the whole transaction.
