plz answer
let us consider there are total 100 computers
from the data we get
number of laptops--30
number of desktops--70

number of computers with >1gb ram--80
number of computers with <1gb ram--20--10% of these are laptop so 2 are laptops hence laptops with more than 1GB ram
are(30-2) or 28
number of desktops with more than 1GB ram (80-28) or 52

hence the percentage of the desktops with more than 1GB of RAM is (52/70)x100 or approx 75%
ans A

If we let x = 100, we have 30 laptops and 70 desktops. Furthermore, 80 computers have more than 1GB of RAM, and 20 computers have less than 1GB of RAM.

Therefore, 20 x 0.1 = 2 are laptops with less than 1GB of RAM, and 18 are desktop with less than 1 GB of RAM. Since there are 70 desktops, 70 - 18 = 52 desktops have more than 1 GB of RAM. So 52/70 x 100 ≈ 75 percent of the desktops have more than 1 GB Of RAM.

Answer: A
