## Bakery DS

At a bakery Lew spent a total of \$6.00 for one of kind of cupcake and one kind of dougnut. How many dougnuts did lew buy ?

1) The price of 2 doughnuts was \$0.10 less than the price of 3 cupcakes

2) The average (mean) price of 1 dougnut and 1 cupcake was \$0.35

SPOILER: Official Answer E Gmat Prep

Quite confusing .. but this is what i think ....
Let y = no. of dougnuts
D = cost of 1 dougnut

x = number of cupcakes
C = cost of 1 cupcake

Question gives
XC + YD = 6

A --- 2D = 3C - 0.1
-- insufficient

B -- D + C = 0.35 * 2 -- Insufficient

Combining A & B , we can find C and D , i.e cost of doughnut and cost of cupcake , but it still isnt sufficient to find x or y ,
Hence E
