Question

ajay sold a chair for rs 1000 at a loss of 20 percent.at what price should he have sold it to gain 10 percent?answer quickly

Answer 1

Let the CP of chair be x

Therefore, loss = 20% of Cp
= 20/100× x
= x/5

SP = CP - loss
1000 = x - x/5
1000 = 4x/5
x = 1000×5/4
x = 1250

CP = 1250

Now let the SP be y
profit = 10% of CP
profit = 10/100 × 1250
= 125

SP = CP + Profit
= 1250 + 125
= 1375

Therefore , he would have to sell the chair at RS 1375 to gain 10% profit

Hope it helps you....
