Question

Janaki sells a washing machine for rs 13500.she loses 20 percentage in the bargain. What was the price at which she bought it?

Answer 1

SP of the Machine = 13500 Rs

He made 20 % loss.

That means he sold the machine at (100-20)% = 80 % of CP

Hence CP = 13500*100/80= 16875

She bought the machine at  Rs 16875

Answer 2

Answer:

Rs 16875/-

Step-by-step explanation:

let the original price of the washing machine be 'x'

13500 is the value which is a result of 20% of the original value being lost.

therefore, 20% of the original value deducted from the original value results in 13500.

hence,

x - (20% of x) = 13500

x - (20/100 × x) = 13500

x - ( 2/10 × x) = 13500

x - (0.2x) = 13500

x can also be written as 1x.

therefore,

1x - 0.2 x = 13500

0.8x = 13500

taking 0.8 to the right hand side of the equation,

x = 13500/0.8

x = 16875/-
