5%gain=Rs70 gain (tea set)     

5%+10% gain=Rs130 gain (both tea & lemon set)                         

10% gain=?(lemon set)             

'Therefore :                                 

Rs gained in both lemon & tea set - Rs gained in lemon set only                                                                   

 130-70=60 .                           

 Therefore Rs gained for lemon set=Rs60

10%=60

P/CP x 100 = 10%

60/CP x 100 = 10%

CP = 600Rs.
