Trends of FDI in India

3. 

If India FDI from OPEC countries was proportionately the same in 1992 and 1997 as the total FDI from all over the world and if the FDI in 1992 from the OPEC countries was Euro 2 million. What was the amount of FDI from the OPEC countries in 1997 ?

[A]. 11
[B]. 10.72
[C]. 11.28
[D]. 11.5

Answer: Option A

Explanation:

Let x be the FDI in 1997.

Then: (2/5.7) = (x/31.36)

x = (2/5.7) x 31.36

x = 11

How is 2/5.7 is coming?

(1992)5.7 proportional to (1997) 31.36.

It means 31.36/5.7=proportionality constant k --------> (1)
Now, x/(2 million) = proportionality constant k -------> (2)
Divide equation 1/2.
then x=11.

2 is mention in the question:

1997 = 2/5.7 as given.
Now 1997 = X/31.36.
2/5.7 = X/31.36,
5.7X = 2*31.36,
5.7X = 62.72,
X = 62.72/5.7,
X = 11.

In the question it's telling that FDI from OPEC is proportionately (ratio) same for the year 1992 and 1997 from the total FDI of that respective year.

So for 1992 - FDI from OPEC/ Total FDI
=> 2/5.7.

Now for 1997- x/31.36.
So it's given that ratio is same which means
2/5.7=x/31.36.

Cross multiple we will get x= 11.
