4. An item was sold for 540 at a loss of 5%. What was its cost price?​

Answer 1

Answer:(3)238.095 & (4) 568.421

Step-by-step explanation:

Answer of question (3):

Let the CP be x

Profit=5%

Then SP=x+5%of x

=x+(5/100)×x=x+(x/20)=21x/20

Given that SP=250

Therefore 250=21x/20

Or,(250×20)/21=x

Or, x=238.095

Answer of question (4):

Given, SP=540

LOSS=5%

CP=?

Let CP be x

Then SP=x-5% of x

=x-(x/20)=19x/20

Now by question,

540=(19x/20)

Or, x=(540×20)/19

Therefore x=568.421
