Solution
C.P. of a T.V. set = Rs. 2500, M.P. = Rs. 3200
Rate of discount = 10%
∴ Total discount = Rs. `3200 xx 10/100` = Rs. 320
(i) Sellin price = Rs. 3200 - Rs. 320 = Rs. 2880
(ii) Gain = S.P. - C.P.
= Rs. 2880 - Rs. 2500 = Rs. 380
∴ Gain% = `("gain" xx 100)/"C.P."`
`= (380 xx 100)/2500`
`= 76/5 = 15 1/5% = 15.2`
