Question

manu sold his tv set at a loss of 20%. if he had bought it for rs21000 find the selling price

Answer 1

Cost price (C.P.) = 21000

20% of 21000 =    21000 x 20/100
                        =   4200

Selling price (S.P.) =  21000 - 4200
                              =  16800


So, Manu sold his T.V. for 16800.

Answer 2

cost price of the TV=21000.
Percentage of loss = 20%.
loss = 20/100×21000
=> 0.2 × 21000
=>4200.

Therefore selling price = 21000 - 4200
=16,800 RS.
