Question

If cp of 25 articles is equal to sp of 30 articles find the loss percent

Answer 1

Step-by-step explanation:

25 cp = 30 sp

1 cp = 30/25 sp

30/25 sp > 1 sp {cross multiplication}

therefore it is a loss [30/25 sp = 1 cp]

loss = cp - sp

=30/25 sp - 1 sp

LCM = 25

loss = 5/25 sp

loss% = {loss/cp} * 100

= {5/25 sp / 30/25 sp} * 100

= {5/25 * 25/30} * 100 {sp gets cancelled}

= 50/3 %

therefore the loss % = 50/3%

Answer 2

Answer

Step-by-step explanation:

CP of 25 articles = SP of 30 articles

Let , SP of 1 article = x

SP of 30 articles = 30x

Sp of 25 articles = 30x

SP of 1 article 30 / 25 = 6/5x

therfore, CPis bigger than SP

There is Loss = 6x/5-x/1=6x-5x/5=x/5

Loss %=x/5/6x/5×100%=Loss/ CP × 100%

5x/30x×100=50/3%
