Question

ram sold a watch at 15% loss if it had for rs 750 more than he would have gain 10%. find cost price of watch

Answer 1

Answer:

CP=3000

Step-by-step explanation:

Given,

ram sold a watch at 15% loss

Let cp=100%

Let selling price is SP1

Loss%=((CP-SP1)/CP)*100

15=100-SP1

SP1=100-15

SP1=85%

if it had for rs 750 more than he would have gain 10%.

Gain/Profit is 10%

Let selling price is SP2

Profit=((SP2-CP)/CP)*100

10=SP2-100

SP2=110%

SP2-SP1=110-85

             =25%

25% difference is by adding 750 more

25%=750

100%=3000  which is CP
