Explanation
| Countries | Population (in million) | GNP (in million Dollars) |
| R | 120 | 2,500 |
| S | 180 | 12,000 |
| T | 60 | 4,000 |
| U | 100 | 6,500 |
| V | 25 | 2,500 |
(a)(i) R, per capita income = \(\frac{2500} {120}\) = $20.83
S, per capita income = \(\frac{12,000} {80}\) = $66.66
T, per capita income = \(\frac{4,000} {60}\) = $65.66
U, per capita income = \(\frac{6,500} {100}\) = $65.00
V, per capita income = \(\frac{2,500} {25}\) = $100.00
(ii) Range $100 - $20.83 = $79.17
(iii) Country V.
(b)(i) R,120 x100 = 24.74%
485 1
S, 180 x100 = 37.11%
485 1
T, 60 x100 = 12.37%
485 1
U, 100 x100 = 20.62%

V, 25 x100 = 5.15%
