here will be profit because SP of 8 articles=CP of 10 articles

Answer 2

Solutions :-


Given :

The cost price of 10 articles is equal to selling price of 8.


Find the LCM of 10 and 8 :-

LCM of 10 and 8 is 40


So,
Cost Price of 10 articles = Rs 40
Selling Price of 8 articles = Rs 40


Now,
Find the Cost price of 1 article :-

C.P of 10 articles = Rs 40
C.P of 1 article = Rs 40/10 = Rs 4


Find the Selling price of 1 article :-

S.P of 8 articles = Rs 40
S.P of 1 article = Rs 40/8 = Rs 5


Selling price is greater than the cost price. Therefore, Profit.


Profit = S.P - C.P
= Rs (5 - 4)
= Rs 1


Profit % = (profit × 100)/C.P %
= (1 × 100)/4 %
= 100/4 %
= 25 %



Hence,
The profit percent is 25%
