WAEC 2021 - ECONOMICS ANSWER
Entire labour force = 30+37+19+12.2+16.1+10.8+15.6+19+10.3 = 170million
(i) Primary sector ==> Mining + Fish farming + food crop production
% of primary sector = (16.1+10.8+15.6)/170 ×100%
= 12.5/170 × 100%
(ii) Secondary sector ==> Shoe production + Fish processing + Baking
% of secondary sector = (30+19+19)/170 × 100%
(iii) Tertiary (%) = 100% - (40+25)%
Ratio = 16.1/30 = 161:300
% Warehousing = 12.2/170 × 100%
(i) Mixed economy
