Question

Juhi sells of washing machine for rupees 13500 she loses 20% in the bargain what was the price at which she bought it

Answer 1

Let the cost be x.
Loss= 20%

x - x*0.2 = 13500
0.8x = 13500
x = 16875

So, the buying price is Rs. 16875

Answer 2

Let the price at which she bought be x.
Then,
x - 20% of x = ₹13500
x - 20x/100 = 13500
(100x - 20x)/100 = 13500
80x/ 100 = 13500
x = 13500×100/80
x = 168.75 × 100
x = ₹16875
Therefore, the price at which she bought it was ₹16875.
