Question

If cost price of 12 articles is equal to the selling price of 10 articles , find gain% or loss%
​

Answer 1

Answer:

20% gain

Step-by-step explanation:

CP of 1 article be Re. 1

CP of 12 articles = Rs. 12   (eqn. 1)

CP of 12 articles = SP of 10 articles   (given condition)

So, SP of 10 articles = Rs.12   (comparison of given condition and eqn. 1)

So, SP of 1 article = (12/10) = Rs. 1.2

Now,

CP = Re. 1

SP = Rs. 1.2

The SP is more than the CP. So, it should be the Gain

Re.1 = 100%

Rs. 1.2 = ? %

= (1.2×100)÷1

= 120

20 numbers more than the 100. So, 20% gain.
