30,000
26,000
8,000
25,000
24,000
Solution:
Total production of HCL, Acer and Toshiba laptops in percentage
= 12% + 8% + 10%
= 30%
ATQ,
20% = 16000
30% = 24000

Q2. What is the ratio of production of laptops HP, Acer and HCL together to the production of laptops Dell and Toshiba together?
23 : 17
23 : 34
17 : 23
46 : 17
15 : 17
Solution:
Required ratio = (28% + 8% + 10%) : (22% + 12%)
= 46 : 34
23 : 17

Q3. The total number of production of laptops of Toshiba and H.P. together is what percent more or less than the total number of production of laptops of Dell and Acer together ?
20% less
25% more
33.33% more
30% more
33.33% less
Solution:

Q4. In the next year the production of laptop of Dell company increased by 50% then find the total production of laptops of Dell and Lenovo together ?
49000
25000
55000
can’t be determined
60000
Solution:
Because the production of laptop of Lenovo is how much percent increase/decrease in the next year not given in question then the data is insufficient to find the production of laptops of both companies together.

Q5. What is the difference between the total production of laptop in Dell and HP together and the production of laptops of Lenovo and HCL together ?
24000
20000
30000
16000
25000
Solution:
Required difference = (50% – 30%) = 20%
In instruction given that 20% = 16000
