    View Answer
      Option C
    Solution:
    Total laptops sold by store B = 48000*(28/100) = 13440
    Dell laptops sold by it = 28000*(32/100) = 8960
    Number of Lenovo laptops sold = 13440 – 8960 = 4480
    Dell laptops sold by store E = 28000*(10/100) = 2800
    Required %= ((4480-2800)*100)/2800 = 60%
  2. What is the ratio between the number of Dell and HP laptops sold by store A?
    A) 49:59
    B) 60:73
    C) 18:91
    D) 70:112
    E) 131:115
    View Answer
      Option A
    Solution:
    Total laptops sold by A  =48000*(18/100) = 8640
    Dell laptops = 28000*(14/100) = 3920
    HP laptops = 8640 – 3920 = 4720
    Required ratio = 3920:4720 = 49:59

    C) 2000
    D) 2400
    E) 3200
    View Answer
      Option D
    Solution:
    Total laptops sold by A and C =(18+15)% of 48000
    = 48000*(33/100) = 15840
    Total laptops sold by E and F = (20+8)% of 48000
