The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.

Ratio of Value of Imports to Exports by a Company Over the Years.

1. 

If the imports in 1998 was Rs. 250 crores and the total exports in the years 1998 and 1999 together was Rs. 500 crores, then the imports in 1999 was ?

[A]. Rs. 250 crores
[B]. Rs. 300 crores
[C]. Rs. 357 crores
[D]. Rs. 420 crores

Answer: Option D

Explanation:

The ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.

Let the exports in the year 1998 = Rs. x crores.

Then, the exports in the year 1999 = Rs. (500 - x) crores.

Therefore 1.25 = 250     =>     x = 250 = 200       [Using ratio for 1998]
x 1.25

Thus, the exports in the year 1999 = Rs. (500 - 200) crores = Rs. 300 crores.

Let the imports in the year 1999 = Rs. y crores.

Then, 1.40 = y     =>     y = (300 x 1.40) = 420.
300

Therefore Imports in the year 1999 = Rs. 420 crores.

Friends here we can use the import and export ratio separately. I think this can help us.

Can we use any option elimination technique in this question?

Sir can you explain clearly?

Can you explain the formulas used to find x and y in imports and exports?

Can you explain the formulas used to find x and y in imports and exports?

Because I am not understanding 250/x and y/300 which formula is used here?

Anyone knows the short tricks of this question?

Import/exp = 1.25 means = 125/100.

So, 250/exp (of 1998) = 125/100.
So exp = 200(of 1998).
So exp of 1999 = 500- 200 = 300.

Similarly,
imp(1999)/300 = 140/100.
imp = 420.

Why did it go from division to multiplication?

Thanks for your explanation @Devesh Sengar.

How it comes 200? Can anyone explain?

Akber Khan said: (May 9, 2020)  
(250/1.25)
= (250*100÷125),
= 25000÷125,
= 1000÷5,
= 200.
