Gce Model Questions Vol1 2019 Economics Question 48
Practice objective / multiple choice question 48 from the 2019 Gce Model Questions Vol1 Economics examination.
The Human Development Index (HDI) is calculated as the geometric mean of three dimension indices: health (\(I_h\)), education (\(I_e\)) and income (\(I_i\)): \(\text{HDI}= (I_h I_e I_i)^{1/3}\). The health index is derived from life expectancy (LE) using \(I_h = \frac{LE-20}{85-20}\). Currently, life expectancy is 55 years, giving \(I_h=0.5385\). The education and income indices are fixed at \(I_e=0.80\) and \(I_i=0.85\). The government wishes to raise the HDI to 0.750 within ten years, assuming only life expectancy can improve. What life expectancy (in years, to one decimal place) must be achieved to meet the target?
