1.	24. A man buys two watches for 800. He sells one at 12% loss and other at 4 gain.On the hole he neither gains nor loses. Find the cost price of each.
Answer» CP= Rs 800,Profit % =4%, loss%=12% To find SP when CP and Profit% is known SP = [(100 + Profit%) / 100]×CP =((100+4)/100)×800 =(104/100)* 800 =Rs 832 ER. RAVI KUMAR ROY.. To find SP when CP and Loss % is known SP = [(100 – Loss %) / 100]CP =((100-12)/100)800 =(88/100)*800 =Rs 704 Total CP=Rs 1600 Total SP= Rs 832+ 704 = 1536 SP of 1 watch = 1536/2 = Rs768 Loss on both the watch= CP-SP=1600 -1536= Rs 64

Answer»

CP= Rs 800,Profit % =4%, loss%=12%

To find SP when CP and Profit% is known

SP = [(100 + Profit%) / 100]×CP

=((100+4)/100)×800

=(104/100)* 800

=Rs 832

ER. RAVI KUMAR ROY..

To find SP when CP and Loss % is known

SP = [(100 – Loss %) / 100]*CP

=((100-12)/100)*800

=(88/100)*800

=Rs 704

Total CP=Rs 1600

Total SP= Rs 832+ 704 = 1536

SP of 1 watch = 1536/2 = Rs768

Loss on both the watch= CP-SP=1600 -1536= Rs 64
