Answer :

1) Given that, cost price = ‘ 750

Expense = Rs. 50


Profit = Rs. 80


Selling price = cost price+ Expense + profit


= 750+50+80


selling price = Rs. 880


Purchase price = cost price+ Expense


= 750+50


= Rs. 800




= 10%


Profit percent = 10%


2) Given that, cost price = ‘ 4500


Expense = Rs. 500


Loss = Rs. 1000


Selling price = cost price+ Expense - loss


= 4500+500-1000


selling price = Rs. 4000


Purchase price = cost price+ Expense


= 4500+500


= Rs. 5000




= 20%


loss percent = 20%


3) Given that, cost price = ‘ 46000


Expense = Rs. 4000


Selling price = Rs. 60000


Purchase price = cost price+ Expense


= 46000+4000


= Rs. 50000


Profit = selling price – purchase price


= 60000- 50000


= Rs. 10000


profit = Rs. 10000




= 20%


Profit percent = 20%


4) Given that, cost price = ‘ 300


Expense = Rs. 50


Profit percent = 12%


Purchase price = cost price+ Expense


= 300+50


= Rs. 350




= Rs. 42


Profit = Rs. 42


Selling price = purchase price + profit


= 350 + 42


= Rs. 392


Selling price = Rs. 392


5) Given that, cost price = ‘ 330


Expense = Rs. 20


Loss percent = 10%


Purchase price = cost price+ Expense


= 330+20


= Rs. 350




= Rs. 35


loss = Rs. 35


Selling price = purchase price - loss


= 350 - 35


= Rs. 315


Selling price = Rs. 315
