1) Cost of production (A + B) by X2 = (15% of
75) crores
Cost of
production of medicine A by X2 = ₹ (2/5 of (15% of 75) crores
= 4.5 crores
Similarly, cost of production of medicine A by X6 =
(3/8 of (8% of 75) crores
= 2.25 crores
Required Ratio = 4.5 / 2.25 = 2:1
2) Cost of production of medicine A by company X2 =
[2/5 of (15% of 75)] crores
=
4.5 crores
Cost of production of medicine B by company X1 = [2/5
of (11% of 75)] crores
= 3.3 crores
=> Total cost = (4.5 + 3.3) crores = 7.8 crores
3) Cost of production of medicine B by company X3 =
[2/3 of (12% of 75)] crores
=
6 crores
Cost of production of medicine B by company X4 =
[4/5 of (5% of 75)] crores
= 3 crores
=> Total cost = (6 + 3) crores = 9 crores
4) It is clear from the pie chart that the cost of
production of both the medicines together by company X5 = (27% of 75) crores
Similarly, we have (from the pie chart) that the production
of both the medicines together by combinations of companies is as follows:
(i) (X1 + X3) = [(11% + 12%) of 75] crores = (23%
of 75) crores
(ii) (X6 + X7) = [ (8% + 22%) of 75] crores = (30%
of 75) crores
(iii) (X4 + X7) = [(15% + 22%)of 75] crores = (27%
of 75) crores
which is same as that for company X5.
(iv) (X2 + X6) = [(15% + 8%) of 75] crores = (23%
of 75) crores
5) Cost of production of medicine B by company X6 =
[ 5/8 of (8% of 75)] crores
=
15/4 crores
Now, Profit earned = 25% of cost of production
= (25% of 15/4) crores
= 93.75 lakhs
6) Profit earned by Company X3 for medicine A
= {30% of [1/3
of (12% of 75)]} crores = 0.90 crores
Profit earned by Company X3 for medicine B
= {24% of [2/3 of (12% of 75)]} crores = 1.44
crores
Total profit earned by Company X3 = (0.90 + 1.44)
crores
= 2.34 crores
7) Profit earned by Company X5 for medicine A
= [28% of {5/8 of (27% of 75}] crores = 3.54 crores
Profit earned by Company X7 for medicine B
= [ 22% of { 1/5 of (22% of 75)}] crores = 0.73
crores
Total profit = (3.54 + 0.73) crores = 4.27 crores
