Answer 1

Answer:

The cost price of a watch is Rs. $444.44$

Step-by-step explanation:

Given : Selling price of a watch = Rs. $400$

             The man had a % loss on selling a watch = $10$%

To find : The cost price of a watch that the man had paid = ?

Solution :

• It is given that the selling price of a watch = Rs. $400$
• The man had a % loss on selling a watch = $10$%
• We have to calculate that the cost price of a watch that the man had paid.
• Let, the cost price of a watch be Rs. $x$.
• To find the cost price of a watch, we have to calculate the % loss.
• According to given condition, the equation becomes

             $10$% of $x+400=x$

             ∴ $\frac{10}{100} *x+400=x$

                 ∴ $\frac{10x+40000}{100}=x$

                  ∴ $10x+40000=100x$

                     ∴ $100x-10x=40000$

                            ∴ $90x=40000$

                              ∴ $x=\frac{40000}{90}$

                               ∴ $x=444.44$ Rs.

•  ∴ The cost price of a watch is Rs. $444.44$
