Question

the selling price of 5 articles is equal to the cost price of 7 articles. find the gain% or loss%​

Answer 1

Answer:

40% profit

Step-by-step explanation:

cost price of 7 = selling price of 5

cp * 7 = sp * 5

where,

cp = cost price of 1 article

sp = selling price of 1 article

so,

sp/ cp = 7/5 (cross multiplication)

profit or loss percent = ((sp/cp)-1)*100

= ((7/5)-1)*100

= (2/5)*100

= 40% profit

Answer 2

Cost price × 9 = Selling price × 5

SP/CP = 7/5

7 -1 ×100

5

40%
