Answer: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%

Given :-

Let the cost price of each card be x

Then, CP of 8 cards = 8x.

SP of 8 cards = CP of 10 cards = 10x.

Thus, CP = R 8x and SP = 10x.

→ Since ( SP ) > ( CP ), there is a gain.

→ Gain = ₹ ( 10x - 8x ) = 2x.

→ Gain% = ( Gain / CP × 100 ) %

= ( 2x / 8x × 100 )% = 25%

hope it works❤
