E | 60 | 50 | 55 | 100 | 110 |
F | 24 | 40 | 60 | 75 | 120 |
37. (a)
Given, import of all countries = ₹ 385 Crore
Now, Export of all countries = 90 + 100 + 65 + 25 + 110 + 120 = 510 = ₹ 510 crore
∴ Profit all countries together = 510 – 385 = 125 = ₹ 125 crore
38. (d)
For country D, import
\(= 45 \times \frac { 2 } { 1 } \)
= ₹ 90 Crore
For country F, import
\(= 24 \times \frac { 1 } { 4 } \)
= ₹ 6 crore
Thus, the total imports of country F and D together = 90 + 6 = ₹ 96 crore
39. (e)
Total export of country B in 2015 = ₹ 50 crore
Total export of country E in 2015 = ₹ 55 crore
∴ Together total export = 50 + 55 = ₹ 105 crore
∴ Total export of country A in 2017
\(= 105 \times \frac { 120 } { 100 }\)
= ₹ 126 crore
Given, import of country A in 2017 = ₹ 92 crore
∴ Profit of country A in year 2017
= Export – Import
= 126 – 92 = ₹ 34 crore
40. (a)
Average export of country E
\(\frac { 60 + 50 + 55 + 100 + 110 } { 5 } = \frac { 375 } { 5 } = 75\)
