Study the following line graph which gives the number of students who joined and left the school in the beginning of year for six years, from 1996 to 2001.
Initial Strength of school in 1995 = 3000.
1997
1998
1999
2000
Correct answer is A
The percentage rise/fall in the number of students who left the school (compared to the previous year) during various years are:
For 1997 = [ (450 - 250)/250 x 100 ] % = 80% (rise).
For 1998 = [ (450 - 400)/450 x 100 ] % = 11.11% (fall).
For 1999 = [ (400 - 350)/400 x 100 ] % = 12.5% (fall).
For 2000 = [ (450 - 350)/350 x 100 ] % = 28.57% (rise).
For 2001 = [ (450 - 450)/450 x 100 ] % = 0%.
Clearly, the maximum percentage rise/fall is for 1997.

Two different finance companies declare fixed annual rate of interest on the amounts invested with them by investors. The rate of interest offered by these companies may differ from year to year depending on the variation in the economy of the country and the banks rate of interest. The annual rate of interest offered by the two Companies P and Q over the years are shown by the line graph provided below.
Annual Rate of Interest Offered by Two Finance Companies Over the Years.
Rs. 594,550
Rs. 580,425
Rs. 577,800
Rs. 577,500
Correct answer is B
Amount received from Company Q after one year on investment of Rs. 5 lakhs in the year 1996
= Rs. [5 + (6.5% of 5)] lakhs
= Rs. 5.325 lakhs.
Amount received from Company P after one year on investment of Rs. 5.325 lakhs in the year 1997
= Rs. [5.325 + (9% of 5.325)] lakhs
= Rs. 5.80425 lakhs
= Rs. 5,80,425.

Rs. 296,200
Rs. 242,200

Rs. 216,000
Correct answer is C
Amount received from Company P after one year (i.e., in 199) on investing Rs. 12 lakhs in it
= Rs. [12 + (8% of 12)] lakhs
= Rs. 12.96 lakhs.
Amount received from Company P after one year on investing Rs. 12.96 lakhs in the year 1999
= Rs. [12.96 + (10% of 12.96)] lakhs
= Rs. 14.256.
Appreciation received on investment during the period of two years
= Rs. (14.256 - 12) lakhs
= Rs. 2.256 lakhs
= Rs. 2,25,600.

Annual Rate of Interest Offered by Two Finance Companies Over the Years.
Rs. 9 lakhs
Rs. 11 lakhs
Rs. 12 lakhs
Rs. 18 lakhs
Correct answer is D
Let Rs. x lakhs be invested in Company P in 2000, the amount invested in Company Q in 2000 = Rs. (30 - x) lakhs.
Total interest received from the two Companies after 1 year
= Rs. [(7.5% of x) + {9% of (30 - x)}] lakhs
= Rs. [ 2.7 - ( 1.5x/100 ) ] lakhs.
Therefore [ 2.7 - ( 1.5x/100 ) ] = 2.43 => x = 18.
