Question

Swapna bought two books for Rs.800 each. She sold one book at a loss of 10% and other at a
profit of 15%. Find the selling price of each and also find the total profit or loss.

Answer 1

Answer :

→ Profit = 1¼%

Explanation :

C. P. (cost price) of the two books ₹800 each.

∴ Total C. P. = 800*2 = ₹1,600.

Now,

One book is sold in 10% loss

So,

→ 800 - (10% of 800)

→ 800 - 80

→ 720

∴ S. P.(selling price) of one book ₹720

And also, another one in 15% profit.

So,

→ 800 + (15% of 800)

→ 800 + 120

→ 920

∴ S. P. of another book ₹920.

We have,

C. P. = 1,600

S. P. = 920 + 720 = ₹1,620

Since,

S. P. > C. P.

There is a gain in whole transaction.

Gain = S. P. - C. P. = 1,620 - 1,600 = ₹20

∴ Gain% = gain*100/C.P.

= 20*100/1600

= 5/4

= 1¼%
