At store W, in June of year X, the price of a cabinet was 20 percent less than it was in July of year X, and at store W, in June of year X, the price of a lamp was 15 percent greater than it was in July of year X. What was the price of the lamp in store W, in June of year X?

(1) In July of year X, the price of the cabinet was $260 greater than the price of the lamp.

(2) The ratio of the price of the cabinet in June of year X to the price of the cabinet in July of year X was 4 to 5.

Statement 1 and 2 are insufficient of itself......I hope thats easy and you may hove no doubt in that

Combining both statement gives

C-L = 260 and 0.8C/C = 4/5

You can noot calcualte the value of C from the proprotion......because c will be cancelled and you will be left out with 0.8 =4/5

had it been 0.8l/c =4/5

than there would have been possible soln....

Consider kudos if my post helps!!
