Question

by selling a tv for ₹18,000 ,a shopkeeper incurs a loss of 10%.what should be the selling price if he had to earn a profit of 10%?

Answer 1

Find the cost price of the tv:

Loss = 10%

Selling Price = 100 - 10 = 90%

Selling Price = ₹18,000

90% = ₹18000

1% = 18000 ÷ 90 = ₹200

100% = 200 x 100 = ₹20,000

Find the price that he needs to sell at:

Profit = 10%

Profit = 10% x ₹20,000 = 0.1 x 20,000 = ₹2000

Selling Price = 20,000 + 2000 = ₹22,000

Answer: He should sell the TV at ₹22,000

Answer 2

sp=18000,

L%=10%,

cp=(100/100-10)×18000

=20000

And , 10%profit so,

110/100+×20000=22000
