Question

salman bought 40 chairs at 175 rupees each. he sold one-fourth of them at a loss of 8%. At what price each must he sell the remaining chairs so as to gain 10% on the whole deal?

Answer 1

S.P=5250+10%of5250 =5250+10/100of5250=₹10500 Ans.

Answer 2

cp of 40 chairs is 4.375..rs
192.5rs would be the amount if he sold all 40 chairs @10%profit...
40.25rsis the amt he received by selling 10 chairs
192.5-(40.25+131.25(cp of remaining chairs))=21..rs
now he must sell remaining 30 chairs @152.25rs...(131.25+21)....its sp would be 152.25÷30=5.075rs...
