Question

Answer 1

Same question I have done in my copy ..... first find cp of first chair by formula cp =100/100+gain % ×sp

Now done same with second one also but formula cp =100/100-loss%

Add sp and sp

Add cp and cp

Now find loss or profit by

If sp is greater then sp - cp

If cp is greater then cp - sp

Now find loss%= (loss /cp ×100)%

or

gain%= (gain /cp ×100)%

Your answer is done ......5/5 koi rok nahi sakta
