1. Study the bar diagram carefully and answer the questions. The bar diagram shows the trends of foreign direct investment (FDI) into India from all over the World (in Rs. crores).

The ratio of investment in 1997 to the average investment is:

A. 2 : 1

B. 1 : 2

C. 1 : 1

D. 3 : 1

Solution:

Average investment
=

\frac{31.36 + 24.23 + 10.22 + 20.16 + 10.15 + 5.7}{6}

\frac{101.82}{6}

= 16.97
Then ratio of average investment to year 1997

\begin{aligned} = \frac{31.36}{16.97} \\ \approx \frac{2}{1} \\ = 2 : 1 \end{aligned}
