Question

The C.P of 5 identical articles is equal to S.P of 4 articles. Calculate the profit percent or loss percent made if all the articles bought have been sold.​

Answer 1

Answer:

$...$

Step-by-step explanation:

Let CP of 1 article= Rs.x

so, CP of 4 article= Rs.4x

and, CP of 5 article= Rs.5x

SP of 4 articles= CP of 5 articles= Rs.5x (given)

Now,

CP of 4 article= Rs.4x. (proved)

SP of 4 article= Rs.5x. (proved)

because, SP is greater than CP

Gain = 5x-4x= Rs.x

Gain %= x*100%/4x=25%

So,

Gain =25%

Answer 2

Answer:

Let CP of 1 article= Rs.x

so, CP of 4 article= Rs.4x

and, CP of 5 article= Rs.5x

SP of 4 articles= CP of 5 articles= Rs.5x (given)

Now,

CP of 4 article= Rs.4x. (proved)

SP of 4 article= Rs.5x. (proved)

because, SP is greater than CP

Gain = 5x-4x= Rs.x

Gain %= x*100%/4x=25%

So,

Gain =25%
