Answer: Option C

Explanation:

The exports are more than imports in those years for which the exports to imports ratio are more than 1. For Company A, such years are 1995, 1996 and 1997.

Thus, during these 3 years, the exports are more than the imports for Company A.

Answer: Option C

Explanation:

In 1997 for Company A we have:

E	= 1.75     i.e.,     E = 1.75I
I

where E amount of exports, I = amount of imports of Company A in 1997.

Now, the required imports I₁ = I + 40% of I = 1.4I.

Required ratio =	E	=	1.75I	= 1.25.
	I1		1.4I

Answer: Option E

Explanation:

Let the amount of imports of Company A in 1998 be Rs. x crores.

Then,	237	= 0.75         x =	237	= 316.
	x		0.75

Amount of imports of Company A in 1998 = Rs. 316 crores.

Answer: Option B

Explanation:

In 1995 for Company A we have:

EA	= 1.75 ... (i)
IA

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

In 1995 for Company B we have:

EB	= 0.75 ... (ii)
IB

[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 =	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.

Answer: Option E

Explanation:

We shall try to find the difference between the imports and exports of Company B for various years one by one:

For 1995: We have

E	= 0.75
I

where E = amount of exports, I = amount of imports in 1995.

E = 0.75I

I - E = 0.75 x I = 0.25I.

Thus, the difference between the imports and exports of Company B in 1995 is dependent on the amount of imports of Company B in 1995.

Similarly, the difference for other years can be determined only if the amount of imports for these years is known.

Since the imports or exports for various years are not know, the differences between and exports for various years cannot be determined.
