Juhi sells a washing machine for Rs 13, 500. She loses 20% in the bargain. What was the price at which she bought it?Can you please explain it in a simple manner.

 cost price = {100/100-loss% * selling price}

=100/100-20 * 13500

=100/80 * 13500

=1350000/80

=135000/8

=Rs.16875

cost price = Rs.16875

20% of Rs 13,500=20/100 *13,500=Rs 2700

therefore, the price of washing machine which she bought = 13,500+2700=Rs16,200

hope u understand

S.P=Rs 13500
Loss%=20
Then,Cost price = {100/100-loss% * selling price}
=100/100-20 * 13500
=100/80 * 13500
=1350000/80
=135000/8
=Rs.16875
Therefore,Cost price = Rs.16875

Another way is as follows:-
Let the cost price of the washing machine be RS x.
then x-20% of x=13500 because sp=cp-loss
so x-20/100*x=13500
x-x/5=13500
4x/5=13500
4x=13500*5
4x=67500
x=67500/4
x=16875
so the washing machine was bought at RS 16875
