(a) 2002
(b) 2003
(c) 2004
(d) 2006
Option (c) is the right answer

(02) Study the following table and answer the questions given below.
Annual income of five schools
(Figures in 1000 rupees)
(i) For school E, what percent of the income of miscellaneous is the income of donation?
(a) 20%
(b) 40%
(c) \frac{1}{4}%
(d) 400%
income of miscellaneous for school E=60
income of donation for school E=15
Percent of the income of miscellaneous is the income of donation is
=\frac{income\ of\ miscellaneous\ for\ school\ E}{income\ of\ donation\ for\ school\ E} \times 100
⟹ \frac{60}{15} \times 100\\
⟹ 400 %
Option (d) is the right answer
(ii) Which school has the highest percentage of income from tuition fee out of its total income?
(a) A
(b) B
(c) C
(d) D
Income of tuition fee for school A=200
Total income for school A=275
Percentage of income from tuition fee out of its total income
=\frac{income\ of\ tuition\ fee\ for\ school\ A}{total\ income\ for\ school\ A} \\\ \\ =\frac{200}{275} \times 100\\\ \\ =72.72 %
Same for
School\ B=\frac{150}{225} \times 100 \\ \\ =66.66% \\\ \\ school\ C=\frac{68}{126} \times 100 \\ \\ =53.96 % \\\ \\ school\ D=\frac{90}{135} \times 100\\ \\ =66.66 %
we see that the highest percentage of tuition fee we get from school A
Option (a) is the right answer
(iii) In case of how many schools, is the income by way of tuition fee ,is less than four times of term fee?
(a) 0
(b) 1
(c) 2
(d) 3
For school A=tuition fee for school A * 4
=200 * 4
=800
=800 > 275, it is greater
Similarly,
For school B=150 * 4
=600
=600 >225, it is greater
for school C=68 * 4
=272
=272 >126, it is greater
for school D= 90*4
=360
=360 >135, it is greater
for school E=65 * 4
=260
=260< 285, it is lesser
we see only in one case school E is the income by way of tuition fee, is less than four times of term fee
Option (b) is the right answer
(iv) Which school has the lowest ratio of income by way of grants and tuition fee?
(a) E
(b) B
(c) D
(d) A
Ratio for school A= \frac{grant\ for\ school\ A}{tuition\ fee\ for\ school\ A}\\ \\ =\frac{19}{200}\\ \\ =0.095\\\ \\
same ratio for B= \frac{32}{150}\\ \\ =0.21 \\\ \\
ratio for D= \frac{12}{90}\\\ \\ =0.13 \\\ \\
ratio for E= \frac{75}{65}\\\ \\ =1.15\\\ \\
we see school A has the lowest ratio of income by way of grants and tuition fee
Option (D) is the right answer
