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

Q1:

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 pf Company B during that year?

A Rs. 190 crores

B Rs. 210 crores

C Rs. 225 crores

D Cannot be determined

ANS:B - Rs. 210 crores

In 1995 for Company A we have:

EA = 1.75 ... (i)
IA
[where EA = amount of exports, IA = amount of imports of Company a in 1995] In 1995 for Company B we have:
EB = 0.75 ... (ii)
IB
[where EB = amount of exports, IB = amount of imports of Company B in 1995] Also, we have EA = 2EB ... (iii) Substituting IA = Rs. 180 crores (given) in (i), we get:         EA = Rs. (180 x 1.75) crores = Rs. 315 crores. Using EA = Rs. 315 crores in (iii), we get:
        EB = EA = Rs. ( 315 ) crores.
2 2
Substituting EB = Rs. ( 315 ) crores in (ii), we get:
2
IB = EB = Rs. ( 315 ) crores = Rs. 210 crores.
0.75 2 x 0.75
i.e., amount of imports of Company B in 1995 = Rs. 210 crores.
