Ans:4
Required ratio = 120/100 *(420+600):80/100*(540+320)
=>6*(1020): 4*(860)
=>153:86

 

2. Number of cars manufactured by company B on March and April together is what percentage more/less than the number of cars manufactured by company A on January and June together?

Ans:1
Required percentage ={(540+360)-(420+540)}/(420+540)*100
=>600/96=6.25%

 

3. If the number of cars manufactured by company B on July is 120% of the average number of cars manufactured by company A for all the months together (Exclude February and march ), and then find the number of cars manufactured by B on July

Ans:2
Required number of cars = 120/100*(420+600+720+540)/4
=>6/5*2280/4=6/5*570=684

 

4. What is the difference between the total number of cars manufactured by company A and the total number of cars manufactured by company B?

Ans:5
Required difference = (420+640+400+600+720 +540)-(560+480+540+360+450+320)
=>3320-2710
=>610

 

5. In which of the following month the difference between the number of cars manufactured by company A and B is maximum?

Ans:4
January = 560-420=140
February =640-480=160

The pie chart shows the percentage distribution of the number of bags sold by six different companies


Total difference is 32% of the total number of bags sold by all the companies together

6. Number of bags sold by company B at profit is what percentage more/less than the number of bags sold by company C at loss?

Ans:4
Total number of bags sold = 320/32*100=1000
Company A:
Total bags = 1000*20/100=200
Given,
Let us take bags sold at loss be x
X+x+80=200
=>2x=120=>x=60
Bags sold at profit = 200-60=140
Bags sold at loss = 60
Similarly find all the bags

Required percentage = (90-40)/40*100=>50/40*100
=>250/2=125%

 

7. What is the ratio of the number of bags sold by company A and C at profit to the number of bags sold by company D and F at loss?

X+x+80=200
=>2x=120=>x=60
Bags sold at profit = 200-60=140
Bags sold at loss = 60
Similarly find all the bags

Required ratio = (140+60): (75+25)=200:100=2:1

 

8. What is the average number of bags sold by all the companies at profit?

Ans:1
Total number of bags sold = 320/32*100=1000
