Q:

The price of commodity X increases by 60 rupees every year, while the price of commodity Y increases by 20 rupees every year. If in 2002, the price of commodity X was Rs. 320 and that of Y was Rs. 740, in which year commodity X will cost 60 rupees more than the commodity Y ?

A) 2011 B) 2014
C) 2012 D) 2017
 
Answer & Explanation Answer: B) 2014

Explanation:

If After p years , commodity X will cost 60 rupees more than the commodity Y, then

320 + 60p = 740 + 20p + 60
=> p = 12

So in year (2002 + 12 = 2014), commodity X will cost Rs.60 more than the commodity Y.

A. Rs.320 Cr            B. Rs.420 Cr            C. Rs.520 Cr            D. Rs.620 Cr

Answer

1. ANSWER : D 


Explanation -  Clearly the exports are more than the imports implies that the ratio of value of imports to exports in less than 1. So years are 1995, 1996, 1997 and 2000. So these are four years 


 


2. ANSWER : A 


Explanation - Clearly from the line graph we can judge it is minimum in year 1997.


 


3. ANSWER : C 


Explanation -  We are given with the ratio of imports and exports in the line graph.
Let the exports from the company in 1996 was x then, 


272/x = 0.85 


=> x = 272/0.85 


=> x = 320

Note: Please not that we are given the ratio of imports to exports, so export will will in denominator .


 


4. ANSWER : D 


Explanation - For calculating the percentage we will need value of exports, imports etc. We are only given with the ratio. So data in Inadequate.


Note: Please note in charts questions, most probably it includes 1 or more than 1 questions which are percentage based. So please clear percentage questions before preparing it. Because this is very scoring section.


 


5. ANSWER : B 


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 = (500-x) crores

=> 1.25 = 250/x [because 1.25 is 1998 ratio]

=> x = 250/1.25 = 200 crore

Thus the exports in the year 1999 were 500 - 200 = 300 crore

Let the imports in the year 1999 = Rs y crore 


Then 1.40 = y/300 


=> y = 1.40 x 300 = 420 crore
