A factory produces one type of widget. This month, the factory raised the price of each widget to X% of the original price. However, the factory only sold Y% as many widgets as last month, and the total revenue from the sale of widgets was equal for last month and this month.

In the table, identify the values of X and Y that are consistent with the information provided. Make only two selections, one in each column.


X Y Value
50
62.5
75
150
160
180

In this IR question my doubt is ,in explanation they mentioned: If the revenues are equal for the two months, then:

wp = (Y/100) × (w) × (X/100) × ( p)

But in question they have written " the factory raised the price of each widget to X% of the original price" so should it not be p+(x/100)*p.

Please clear this doubt

Hi KARISHMA315,

Please note the wording.

Raised by x% => p + xp/100 but Raised to x% => px/100

Hope this helps.
