Answer:2. Amina buys a book for * 275 and sells it at a loss of 15%. How much does she sell it for?

5. In a public examination 90% students passed and 8,800 students failed. How many students

appeared and how many passed?​

Step-by-step explanation:

Solution:

The cost of a book = Rs. 275

Loss percent = 15%

Loss = Loss% of C.P. = 15% of Rs. 275

= \frac{15}{100}\times275=Rs.\ 41.25  

100

15

​  

×275=Rs. 41.25

Therefore, S.P. = C.P. – Loss

= 275 – 41.25 = Rs. 233.75

Hence, Amina sells a book for Rs. 233.75
