Solution & Step-by-step Explanation

Let the imports and exports in year Y be represented as I
Y

and E
Y

respectively.

Given for 2012:

E
2012


I
2012



=0.7
I
2012

=1100 crores
So,

E
2012

=
0.7
I
2012



=
0.7
1100

=
7
11000

≈1571.43 crores
We are given that the combined exports of 2012 and 2013 is Rs. 5200 crores:

E
2012

+E
2013

=5200
E
2013

=5200−
7
11000

=
7
36400−11000

=
7
25400

 crores
For 2013, the ratio of imports to exports is given as 0.8:

E
2013


I
2013



=0.8
I
2013

=0.8×E
2013


I
2013

=0.8×
7
25400

=

20320

≈2902.85 crores
Rounding off to the nearest whole integer, we get 2903 crores.
