Question

If the cost price of 10 greeting cards is equal to the selling price of 8 greeting cards. Find the gain or loss %.please do not give links.

Answer 1

let the c.p. of 1 card be rs x.
so, the c.p. of 8 cards=rs 8.
since, the s.p. of 8 cards= the c.p. of 10 cards= rs 10.
s.p.>c.p.
so, gain=10-8=rs2
so,gain%=2/8×100%=25%

Answer 2

Answer:

25 %

Step-by-step explanation:

Let the cost price of 1 greeting card be Re. 1

Cost price of 1-0 Greeting Cards = Rs.10

Since we are given that the cost price of 10 greeting cards is equal to the selling price of 8 greeting cards.

So, S.P. of 8 cards = rs.10

C.P. of 8 cards = Rs.8

Since S.P.> C.P.

So, Profit Case

Profit = S.P. - C.P. = 10 - 8 = Rs. 2

Profit % = $\frac{PROFIT}{CP} \times 100$

Profit % = $\frac{2}{8} \times 100$    

Profit % = $25$    

Hence the gain % is 25 %
