Can you please assist with this IR question? This is from MGMAT CAT:
OA:
1st answer: [spoiler] 1/3[/spoiler]
2nd answer: 45
I was clear with the 2nd answer. Just was not clear how the 1st answer was calculated. Thanks for your help.
The red rectangle = the two bedrooms.
Question: The COMBINED AREA of the two bedrooms represents approximately what percentage of the apartment's INDOOR square footage?
Total area of the two bedrooms = b*h = 19.5 * 13.5.
Total area of the indoor space = b*h = 19.5 * 41.
bedrooms/total = (19.5 * 13.5)/(19.5 * 41) = 13.5/41 ≈ 13/39 ≈ 1/3.
