Apartment Building Rooms

There are three sizes of apartments in the new building on the housing estate. One-sixth of the total number of apartments are four-room apartments, and one-third of the rest are two-room apartments. There are 160 three-room apartments. How many four-room and how many two-room apartments are there in the house?

Final Answer:

a =  30.0625
b =  -9.6875

Step-by-step explanation:

n/6+1/3 (1n/6)+160=n 0.888889n=160.333333 98n=3481 8n=1443 n=1443/8=180.375  a=n/6=180.375/6=16481=30161=30.0625

n/6 + 1/3·(1-n/6) + 160 = n

5.333333n = 962


n = 962/5.33333333 = 180.375

n = 1443/8 = 180.375

Our simple equation calculator calculates it.
b=1/3 (1n/6)=1/3 (1180.375/6)=16155=91611=9.6875
