Juhi sells a washing machine for Rs 13,500. She loses 20% in the bargain. What was the price at which she bought of it?

Answer:

Juhi sells a machine for Rs 13,500 She loses in bargain =20% The price she bought it be x. As here/       S.P - ?13/500 Loss % = 20% \[\therefore \] CP =? Loss = C.E - S.E                                                                                                            Loss = x - 13,500           ... (1) Here, Loss % = 20% \[\because \]Loss% =\[\frac{Loss}{C.P}\times 100\] \[\therefore \] 20 =\[\frac{Loss}{X}\times 100\]                                                                                                      \[\frac{20x}{100}=Loss\]               ... (2) Placing value of (2) in (1), We get \[\frac{20x}{100}=[x-13,500]\] 20x = (x- 13500)100 20x = 100x-1350000 13, 50, 000 = (100 - 20)x               13, 50, 000 = 8x                                                                                                                                  x =\[\frac{13,50,000}{80}\]                     x= Rs 16,875.
