### 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
