Answer 1

Step-by-step explanation:

Given a watch when sold at a profit of 6% yields Rs.870 more than when it is sold at a loss of 6% .Find the cost price of the watch

• Let the cost price of the watch be m  
• So profit is 6% = 0.06
• So selling price is 1.06 m--------------1
• So cost price is m
• Loss is 6%
• Now selling price will be 100 – 6 = 94 = 0.94 m------------2
• According to the question a watch sold at profit 6% yields 870 more.
• So Equation 2 -  1 will be
•                       1.06 m – 0.94 m = 870
•                                0.12 m = 870
•                          Or m = 870 / 0.12
•                           So m = 7250
• Therefore the cost price of the watch is Rs 7250

Answer 2

Given,

When sold at a profit of 6% = rs 870 more than when sold at a loss of 6%

To find,

The cost price of the watch

Solution,

Let the cost price of the watch be m  

So profit is 6% = 0.06

So selling price is 1.06 m--------------1

Loss is 6%

selling price = 100 – 6 = 94

= 0.94 m------------2

   According to the question, a watch sold at a profit of 6% yields 870 more.

So Equation 2 -  1 will be

                         1.06 m – 0.94 m = 870

                                  0.12 m = 870

                            Or m = 870 / 0.12

                             So m = 7250

Therefore the cost price of the watch is Rs 7250
