Answer: 16875
Step-by-step explanation:
Let the price of the washing machine be x.
Since she loses 20% in the bargain, this implies that she sold it at (100% - 20%) = 80%.
Therefore, 80% of x = 13500
0.8 × x = 13500
0.8x = 13500
Divide both side by 0.8
0.8x/0.8 = 13500/0.8
x = 16875
Therefore, the price at which she bought the washing machine is 16875 rupees.
