6. Directions(6-10): Following pie-chart shows the percentage distribution of total items (Item A and Item B) produced by six companies (P,Q,R,S,T and U) and the table shows the ratio of A to B and percentage sale of A and B.
Total items = 16 lakh

7. What is the average number of A items sold by all six companies together?
88500
75080
89680
69950
95000
Option C
A items sold by P = 16*(24/100)*(5/8)*(65/100)
= 1.56 lakh
Similarly,
Total A items = 1.56 + 0.896 + 0.6912 + 1.44 + 0.4096 + 0.384
= 5.3808 lakh
Average = 5.3808/6
= 0.8968 lakh
= 89680

8. The number of items sold by Company P is what percentage of the number of A items sold by Company U?
320.11%
415.02%
520.20%
406.25%
300.05%
Option D
A sold by P = 156000,

2.24 lakh
3.23 lakh
4.00 lakh

15800
34500
15500
25600
26000
Option D
Total = 16 Ã— (8/100) = 1.28 lakh,
Item A = (1.28/5)* 3= 0.768
Item B = (1.28/5)*2 = 0.512
Diff = 0.768 â€“ 0.512 = 0.256 lakh
= 25600

11. What is the difference between the number of A items sold and the number of B items sold by Company T?
12350 lakhs
15600 lakhs
32560 lakhs
20000 lakhs
14560 lakhs
Option E
Item A = 16*( 7/100)*( 4/7)* (64/100) = 0.4096
Similary, Item B = 0.2640
