Question

The cost price of 10 articles is equal to selling price of 15 articles. Find the loss percent.

Answer 1

Answer:

50% is the right answer, hope it helps you.

Step-by-step explanation:

In the most easiest way,

10 articles =100%

So , 15 articles =150%.

Loss=SP-CP

Loss=150%-100%

Loss=50%

Or maybe this is right

Answer:

33.33% or 1/3 is right

Step-by-step explanation:

Ratio of cp : sp=10:15

= 2:3

Loss= sp-cp=3-2=1

So Now, the loss in ratio is 1 :3

it means 1/3=33.33% is loss.

Answer 2

Answer:

The cost price = cp

selling price = sp

so , cp = 10 ; sp = 15

10 × cp = 15 × sp

sp / cp = 10 / 15

sp / cp -1 = 10 / 15 -1

we must take lcm of both

sp - cp / cp = 10 - 15 / 15

= 5 / 15

=> 5 / 15 × 100 = 100 / 3 is the loss percent
