Answer : Option B

Explanation :

In 1995 for Company A we have:

\(\frac { EA } { IA }\) = 1.75 ....(i)

[where E_A = amount of exports, I_A = amount of imports of Company a in 1995]

In 1995 for Company B we have:

\( \frac { EB } { IB } \) = 0.75.. (ii)

[where E_B = amount of exports, I_B = amount of imports of Company B in 1995]

Also, we have E_A = 2E_B ... (iii)

Substituting I_A = Rs. 180 crores (given) in (i), we get:

        E_A = Rs. (180 x 1.75) crores = Rs. 315 crores.

             Using E_A = Rs. 315 crores in (iii), we get:

EB = \( \frac { EA} { 2 } \) = Rs .[ \(\frac { 315 } { 2 }\)] crores

Substituting E_B = Rs.[  \(\frac { 315 } { 2 }\)] crores in (ii), we get:

I_B = \(\frac { E B } { 0.75 }\) = Rs .[ \(\frac { 315 } { 2 *0.75 }\)] crores = Rs. 210 crores.

i.e., amount of imports of Company B in 1995 = Rs. 210 crores.
