Directions: Study the following pie chart information carefully and answer the questions given beside:


The following chart shows the percentage purchase of 5 different people P, Q, R, S and T done for upcoming festivals.

No. of total items purchased = 4700

1
What is the difference between the total purchase of items made by R and T together and the total purchase of items made by P and S together?
» Explain it
B
Total purchase of items made by R = 12% of total purchase 
 
Total purchase of items made by T = 16% of total purchase 
 
Similarly, 
 
Total purchase made by P = 18% of total purchase
 
Total purchase made by S = 15% of total purchase
 
Reqd difference = (15% + 18%) of total purchase - (16% + 12%) of total purchase = (33% - 28%) of total purchase = 5% of total purchase
 
= 5% of 4700 = 235.
 
Hence, option B is correct. 

2
What is the ratio of the total purchase made by P, R and T together to that of S and Q together?
» Explain it
A
Total purchase made by P, R and T together = (18 + 12 + 16)% of total purchase = 46% of total purchase

And the total purchase made by S and Q together = (15 + 35)% of total purchase = 50% of total purchase

∴   Reqd ratio =  46% of total purchase  =  46
50% of total purchase 50

= 23 : 25.
Hence, option A is correct.
 
3
If Q pays Rs. 6300 for his total purchase then how much money P has to pay for his purchase? 
» Explain it
D
If Q pays 6300 for 35% purchase

Let, P pays Rs. x for 18% purchase

Therefore, 35% ≡ 6300

18% ≡ x

x =   6300 × 18  = 3240
35

Hence, P has to pay Rs. 3240 for their purchase.

Hence, option D is correct.
 
4
Total purchase made by R is what percent less than the purchase made by S?
» Explain it
C
Total purchase pecentage of R = 12%

And the total purchase percentage of S = 15%

Reqd% =  15 – 12  × 100 =  3  × 100 = 20%
15 15

Hence, R is 20% less than S.

Therefore, option C is correct.
 
5
Find the central angle of the purchase made by S ?
» Explain it
B
As, we know that the whole pie is 360°

therefore, 15% will be 15% of 360

=   15  × 360 = 54°
100

Hence, option B is correct.
