=  \(\frac{ 7.13}{24.23}\) × 100

= 29.42%

2. 1994

Percent increase in FDI =  \(\frac{12.16 - 10.15}{10.15}\) × 100

=  \(\frac{ 2.01}{10.15}\) × 100

= 19.80%

3. 1996

Percent increase in FDI =  \(\frac{24.23 - 10.22}{10.22}\) × 100

=  \(\frac{14.01}{10.22}\) × 100

= 137.08%

4. 1993

Percent increase in FDI =  \(\frac{10.15 - 5.7}{5.7}\) × 100

=  \(\frac{ 4.45}{5.7}\) × 100
