Question

Sujat sold 2 books at rs 1200 each she made a profit of 20 % on a book and 20 % loss another book find the over all profit percentage​

Answer 1

Answer:

0% he didn't get profit or loss

Step-by-step explanation:

Profit % = $\frac{profit(amount)}{C.P}$×100

profit amount of first book = 1200 + 1200×20/100

                                            = 1200+240

                                            = 1440

loss amount of seconf book = 1200 - 1200×20/100

                                               = 1200 - 240

                                               = 960

Total C.P = 1200+1200 = 2400

Total amount he selled for = 1440 + 960

= 2400

Profit Percentage = 0/2400 × 100

=0%

Therefore, he didn't get profit or loss

Answer 2

sujat had a loss

Step-by-step explanation:

• sujat sold first book at 20% profit in Rs 1200

= cost price of first book =

$\frac{1200}{100 + 20} \times 100 = rs \: 1000$

• he sold second book at 20 % loss in Rs 1200

= cost price of second book =

$\frac{1200}{100 - 20} \times 100 = rs \: 1500$

=> total CP of books =

$1000 + 1500 =rs \: 2500$

Total SP of books = 2400

Loss% =

$\frac{2500 - 2400}{2500} \times 100 = 4$

• therefore sujat had a loss of 4%
