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


4.
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?
Rs. 190 crores
Rs. 210 crores
Rs. 225 crores
Cannot be determined
Answer: Option
Explanation:

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.

A= 175/100 & B=75/100.
180 * 175/100= 315/2 * 100/75 = 210.

In, 1995.

A -> E/I =1.25.
E=2x.
I=180.

B-> E/I=0.75.
E=x & I=?


E=(1.75 )I.
2x = 1.75 * 180
x = 157.5
I = 157.5 ÷ 0.75 = 210.
