Correct Answer: Option n
Explanation:
(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 x 100 = 24.74%
485 1
S, 180 x 100 = 37.11%
485 1
T, 60 x 100 = 12.37%
485 1
U, 100 x 100 = 20.62%
485 1
V, 25 x 100 = 5.15%
