Bar Graph Question for Data Interpretation of Quantitative Aptitude 1

  • 1. The foreign exchange reserves in 1997-98 was how many times that in 1994-95

    1. 1.5
    2. 2
    3. 3.5
    4. 2.6
    Answer :

    Option A

    Explanation:

    \begin{aligned}
    \text{Required Ratio =} \\
    \frac{5040}{3360} = 1.5
    \end{aligned}

  • 2. What was the percentage increase in the foreign exchange reserves in 1997-98 over 1993-94 ?

    1. 80%
    2. 90%
    3. 100%
    4. 110%
    Answer :

    Option C

    Explanation:

    Foreign exchange reserve in 1997-98 = 5040 million US $
    Foreign exchange reserve in 1993-94 = 2520 million US $

    Increase = 5040 - 2520 = 2520 million US $
    \begin{aligned}
    \text{Percentage Increase =} \\
    \frac{2520}{2520}*100 = 100 \%
    \end{aligned}

  • 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
    Answer :

    Option D

    Explanation:

    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 :
    \begin{aligned}
    \text{i. For year 1992-93 =}\frac{3720-2640}{2640}*100 \\
    = 40.91\% \\
    \text{ii. For year 1994-95 =}\frac{3360-2520}{2520}*100 \\
    = 33.33\% \\
    \text{iii. For year 1996-97 =}\frac{4320-3120}{3120}*100 \\
    = 38.46\% \\
    \text{iv. For year 1997-98 =}\frac{5040-4320}{4320}*100 \\
    = 16.67\% \\
    \end{aligned}

  • 4. The foreign exchange reserves in 1996-97 were approximately what percent of the average foreign exchange reserves over the period under review ?

    1. 80%
    2. 100%
    3. 125%
    4. 130%
    Answer :

    Option C

    Explanation:

    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 =
    \begin{aligned}
    \left( \frac{4320}{3480}*100\right)\%
    = 125\%
    \end{aligned}

  • 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. 3:5
    2. 2:3
    3. 4:7
    4. 3:7
    Answer :

    Option A

    Explanation:

    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
