Answer the questions based on the given line graph.

Ratio of Exports to Imports (in terms of money in Rs. crores) of Two Companies Over the Years

In 1995, the export of Company A was double that of Company B. If the imports of Company A during the year was Rs. 180 crores, what was the approximate amount of imports of Company B during that year?

Rs. 190 crores

Rs. 210 crores

Rs. 225 crores

Cannot be determined

Correct answer is B

In 1995 for Company A we have:

E_A/I_A = 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:

E_B/I_B = 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:

E_B = E_A/2 = Rs. ( 315/2 ) crores.

Substituting E_B = Rs. ( 315/2 ) crores in (ii), we get:

I_B = E_B/0.75 = Rs. ( 315/(2 x 0.75) ) crores = Rs. 210 crores.

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