Question

A man buys a television for 6800 rupees for how much should he sell it so as to lose 5%on it

Answer 1

10% of 6800 = 680
5% of 6800 = 340
...
6800 +.1(6800) = price to gain 10%
6800 + 680 = $7,480 price to gain 10%
...
6800 - .05(6800) = price with 5% loss
6800 - 340 = $6,460 price with loss of 5%

Answer 2

S.P=100-loss%*C.P/100
      =95*6800/100
      =Rs.6460Ans.
