Answers With Solutions :
1.    Percentage of his expenditure spent on
rent =15%
Percentage of his expenditure spent on transport and food =30%
 30%−15%=15% =
Rs 4500
Monthly expenses: 
= 100%  = ( 100/15) X 4500
= Rs. 30,000

2.    Let his monthly income be Rs x.
Original savings = Rs. (
10/100)x
New Savings = ( 10/100)x +
20/100(10x/100)
= Rs. ( 12/100)x
Original expenditure = x –
(10/100)x
= Rs. ( 90/100)x
New expenditure :
= (90/100)x – (20/100) (
90x/100)
= Rs. ( 72/100)x
Required  percentage :
[(12x/100)/(72x/100)] x
100
= 16.66%

3.    Expenditure on entertainment:
=20%of(35% of others)=7% of the total expenses
 2100=7% of
total expenses
Also education accounts
for 20% of the total expenses.
Expenditure on
education: 
= 20% of the total= Rs [
2100 x ( 20/7)]
= Rs. 6,000

4.    Total expenditure on rent and others:
=15%+35%
=50%
Required angle = ( 50/100)
x 3600
= 1800

5.    Decrease in expenditure on
‘others’:
=10,500−10,290= Rs 210
initial
expenditure on clothes: 
= 210 (100/10)
= Rs. 2100
ð 
Required
percentage:
= ( 2100/10,500) x 100
= 20%

6.    (1)
Explanation: Let analyse the graph before
answering question.
Number of students in 1995 = 3000 [given]
Number of students in 1996 = 3000-250+350 = 3100
Number of students in 1997 = 3100-450+300 = 2950
Number of students in 1998 = 2950-400+450 = 3000
Number of students in 1999 = 3000-350+500 = 3150
Number of students in 2000 = 3150-450+400 = 3100
Number of students in 2001 = 3100-450+550 = 3200
Above analysis will help us solving problems for this line graph.
Lets be back on question now,
Percentage increase in strength of the school from 1997 to 1998 will be,
= ((3000−2950)/2950
100)%=1.69%
So this is approx equal to
1.7%

Explanation: Number of students in 1995 = 3000
[given]
Number of students in 1996 = 3000-250+350 = 3100
Number of students in 1997 = 3100-450+300 = 2950
Number of students in 1998 = 2950-400+450 = 3000
Number of students in 1999 = 3000-350+500 = 3150
8.    (4)
Explanation: Number of students in 1995 = 3000
[given]
Number of students in 1996 = 3000-250+350 = 3100
Number of students in 1997 = 3100-450+300 = 2950
Number of students in 1998 = 2950-400+450 = 3000
Number of students in 1999 = 3000-350+500 = 3150
Number of students in 2000 = 3150-450+400 = 3100
Number of students in 2001 = 3100-450+550 = 3200
From from above options we find in 1996 and 2000 number of students was same
i.e. 3100
9.    (4)
Explanation: Number of students in 1995 = 3000
[given]
Number of students in 1996 = 3000-250+350 = 3100
Number of students in 1997 = 3100-450+300 = 2950
Number of students in 1998 = 2950-400+450 = 3000
Number of students in 1999 = 3000-350+500 = 3150
Number of students in 2000 = 3150-450+400 = 3100
Number of students in 2001 = 3100-450+550 = 3200
In 2001 students = 3200
In 1998 students = 3000
Required Percentage =(3000/3200100)%=93.75%
