Asked by 015tanmaysharma | 03 Jul, 2018, 20:05: PM
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.
