QUIZ QUIZ ON D.I

Directions ( 1 - 5): The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991-92 to 1998-99. Answer the questions based on graph.





1.    The foreign exchange reserves in 1997-98 was how many times that in 1994-95
(1) 1.5                                (2) 3
(3) 2.5                                (4) 2

2.    What was the percentage increase in the foreign exchange reserves in 1997-98 over 1993-94 ?
(1 ) 95 %                           (2) 110%
(3) 100%                           (4) 120%

3.    FOr which year, the percent increase of foreign exchange reserves over the previous year is the highest ?
(1) 1994-95
(2) 1995-96
(3) 1998-99
(4) 1992-93

4.    The foreign exchange reserves in 1996-97 were approximately what percent of the average foreign exchange reserves over the period under review ?
(1) 82%                             (2) 90%
(3) 110%                           (4) 125%

5.    The ratio of the number of years, in which the foreign exchange reserves are above the average reserves, to those in which the reserves are below the average is:
(1) 4: 5                               (2) 3 : 5
(3) 4 : 7                              (4) 7 : 5



ANSWERS:
1.    (1) Required Ratio =5040/3360=1.5

2.    (3) Foreign exchange reserve in 1997-98 = 5040 million US $
Foreign exchange reserve in 1993-94 = 2520 million US $
Increase = 5040 - 2520 = 2520 million US $
Percentage Increase =(2520)/2520 X 100=100%

3.    (4) Before solving this, put a clever eye on the chart, just calculate for those years which are actually having increase if we compare to previous year.
These years are 1992-93, 1994-95, 1996-97, 1997-98
So lets calculate the percentage increase of these years compared to previous years :
.i. For year 1992-93 =(3720−2640)/2640 x 100=40.91%

ii. For year 1994-95 =(3360−2520)/2520 X 100=33.33%
iii. For year 1996-97 =(4320−3120)/ 3120∗100=38.46%
iv. For year 1997-98 =(5040−4320)/4320 X 100=16.67%

4.    (4) First get the average of these 8 years.
which is,
1/8(2640+3720+2520+3360+3120+4320+5040+3120)
= 3480 million US $
Foreign exchange reserves in 1996-97 = 4320 million US $
Required Percentage =
(4320/3480 x 100)%=125%


5.    (2) : Average foreign exchange reserves over the given period is = 3480 million US $
The country had reserves above 3480 million US $ during the years 1992-93, 1996-97 and 1997-98. So three years is was above the average and for rest of five years it was below the average
So required ratio is
3:5

We want banking nd economics sections
Almost every candidate aware about how to solve DI . Agar calculation mistake naa ho to.

But there is awareness about banking /econo.. just basics is not enough this yr

Yaa humara luck saath de kyunki paper level ( GA section ) bhaut differr hai.

So provide banking/economics/computer section in theortical/ PDF way not in ojective .

option 2 is 100% right,
becoz
Statement 1 : No eyes are ears is 'E' type
Statement 2: All ears are drums is 'A' type
so rule is E+A= O (by study)
so ans is conclusion II Some drums are not eyes.
and from Statement:All drums are sound immediate inference is Conclusion IV Some drums are sound.

So option 2 is definitely right.

II, III & IV follow

i/iii and ii follows

Roshan Rocky said...

You may check for complimentary pairs(AO,IO,IE) if their predicate and clauses are the same. In this question, Conclusion 1 which is an A type and Conclusion 2(O type) and both these statements have same predicate and clause. Thus you could Conclude that Either 1 or 3 with Conclusion 2 and 4 which is definitely true. ( Please note that I have just followed the RULES and do let me know if you got any more clarifications)
Thanks
