Because "the original price of the two brands is the same", we can set this original price as X, and buy back a dress at a 50% discount, that is, 50% discount; The other one was bought at a 40% discount, that is, at a 60% discount. It is known that * * * spent 132 yuan, so how much is 132 (50%X+60%X)?

Column type:

(50%X+60%X)= 132

1 10%X= 132

X= 132÷ 1 10%

x = 132× 100/ 1 10

X= 120

Answer: The original price of these two brands is 120 yuan.

Check calculation:

120×50/ 100=60 yuan.

120×60/ 100=72 yuan.

* * * 60+72= 132 yuan.
