Josie's land is to be divided into three parcels. If the larger parcel is 60 percent of the total and the smaller parcels are the same size, what is the number of acres in one of the smaller parcels?
(1) The combined size of the larger parcel and one of the smaller parcels is 416 acres.
(2) The size of the larger parcel is 312 acres.
Given:
1. Josie's land is to be divided into three parcels.
2. The larger parcel is 60 percent of the total and the smaller parcels are the same size.
Let the total land size be x,
Larger parcel size = .6x
Smaller parcel size = (x - .6x)/2 = .2x
Asked: What is the number of acres in one of the smaller parcels?
(1) The combined size of the larger parcel and one of the smaller parcels is 416 acres.
.6x+ .2x = .8x = 416 acres
Number of acres in one of the smaller parcel = .2x = .8x/4 = 416/4= 104 acres
SUFFICIENT
(2) The size of the larger parcel is 312 acres.
Size of larger parcel = 312 acres = .6x
Number of acres in one of the smaller parcel = .2x = .6x/3 = 312/3 = 104 acres
SUFFICIENT
