Answers and Solutions
1.2
Let expenditure =x
65% of x = 8,12,500
x=12,50,000
Income = Expenditure + Profit
= 12,50,000 + 8,12,500
= 20,62,500
2. 3
Let the expenditure of X= expenditure of Y= a
Income of X = 170% of a
= 1.7 a
Income of Y= 155% of a
= 1.55 a
Ratio = 1.7//1.55 = 34/31
3.2
Let the amount invested by Y =x
And amount invested by X=2x
x+2x=27
x=9
Expenditure of X=2x=18
Expenditure of Y=x=9
Profit earned by X= 75% of 18=13.5
Profit earned by Y= 80% of 9 = 7.2
Total profit earned by two companies = 20.7
4.1
Let the investment of X in 2012=x
And investment of X in 2013 =x
Income of X in 2013 =24
Income of X in 2013= 160% of x = 1.6x [ 60% Profit]
1.6 x=24
x =15
profit in 2012= 45% of 15=6.75
profit in 2013= 60% of 15 = 9
Difference = = 2.25
5.4
Investment of X in 2015 = 25
Profit of X in 2015 = 90% of 25 = 22.5
Investment of Y in 2015= 25
Profit of Y in 2015 = 70% of 25 = 17.5
Average profit =40/2=20
