Seven years ago,
Age of Aftab = x - 7
Age of his daughter = y - 7
According to the given condition,

Three years hence,
Age of Aftab = x + 3

Concept insight: In order to represent a given situation mathematically, first see what we need to find out in the problem. Here, Aftab and his daughter's present age needs to be found so, so the ages will be represented by variables x and y. The problem talks about their ages seven years ago and three years from now. Here, the words 'seven years ago' means we have to subtract 7 from their present ages, and 'three years from now' or 'three years hence' means we have to add 3 to their present ages. Remember in order to represent the algebraic equations graphically the solution set of equations must be taken as whole numbers only for the accuracy. Graph of the two linear equations will be represented by a straight line.

Here, note that the coordinates of the intersection of lines with y-axis is taken and not with x-axis, this is because the question says to find the triangle formed by the two lines and the y-axis.

Also, the number of skirts is four less than four times the number of pants purchased". Help her friends to find how many pants and skirts Champa a bought.
(i) Let the number of girls and boys in the class be x and y respectively.
According to the given conditions, we have:
x + y = 10
x - y = 4
x + y = 10 x = 10 - y
Three solutions of this equation can be written in a table as follows:
x | 4 | 5 | 6 |

y | 1 | 0 | -1 |
The graphical representation is as follows:
From the graph, it can be observed that the two lines intersect each other at the point (7, 3).
So, x = 7 and y = 3.
Thus, the number of girls and boys in the class are 7 and 3 respectively.
(ii) Let the cost of one pencil and one pen be Rs x and Rs y respectively.
According to the given conditions, we have:
5x + 7y = 50
7x + 5y = 46

Three solutions of this equation can be written in a table as follows:
x | 8 | 3 | -2 |
y | -2 | 5 | 12 |
The graphical representation is as follows:
From the graph, it can be observed that the two lines intersect each other at the point (3, 5).
So, x = 3 and y = 5.
Therefore, the cost of one pencil and one pen are Rs 3 and Rs 5 respectively.
(iii)
Let us denote the number of pants by x and the number of skirts by y. Then the equations formed are:
y = 2x - 2 ...(1)
and y = 4x - 4 ...(2)
Let us draw the graphs of Equations (1) and (2) by finding two solutions for each of the equations.
They are given in Table
x | 2 | 0 |
y = 2x - 2 | 2 | -2 |
x | 0 | 1 |
y = 4x - 4 | -4 | 0 |
Plot the points and draw the lines passing through them to represent the equations, as shown in fig.,
The two lines intersect at the point (1,0). So, x = 1, y = 0 is the required solution of the pair of linear equations, i.e., the number of pants she purchased is 1 and she did not buy any skirt.
Concept insight: Read the question carefully and examine what are the unknowns. Represent the given conditions with the help of equations by taking the unknowns quantities as variables. Also carefully state the variables as whole solution is based on it. On the graph paper, mark the points accurately and neatly using a sharp pencil. Also, take at least three points satisfying the two equations in order to obtain the correct straight line of the equation. Since joining any two points gives a straight line and if one of the points is computed incorrect will give a wrong line and taking third point will give a correct line. The point where the two straight lines will intersect will give the values of the two variables, i.e., the solution of the two linear equations. State the solution point.

(i) For the two lines a1x + b1x + c1 = 0 and a2x + b2x + c2 = 0, to be intersecting, we must have
So, the other linear equation can be 5x + 6y - 16 = 0
(ii) For the two lines a1x + b1x + c1 = 0 and a2x + b2x + c2 = 0, to be parallel, we must have
So, the other linear equation can be 6x + 9y + 24 = 0,
(iii) For the two lines a1x + b1x + c1 = 0 and a2x + b2x + c2 = 0 to be coincident, we must have
So, the other linear equation can be 8x + 12y - 32 = 0,
Concept insight: In order to answer such type of problems, just remember the conditions for two lines to be intersecting, parallel, and coincident. This problem will have multiple answers as their can be many equations satisfying the required conditions.

The ages of two friends Ani and Biju differ by 3 years. Ani's father Dharam is twice as old as Ani and Biju is twice as old as his sister Cathy. The ages of Cathy and Dharam differs by 30 years. Find the ages of Ani and Biju.
The difference between the ages of Ani and Biju is given as 3 years. So, either Biju is 3 years older than Ani or Ani is 3 years older than Biju.
Let the age of Ani and Biju be x years and y years respectively.
Age of Dharam = 2 × x = 2x years
x - y = 3 ... (1)


Age of Biju = 19 - 3 = 16 years
Case II: Biju is older than Ani by 3 years
y - x = 3 ... (3)

Adding (3) and (4), we obtain:
3x = 63
x = 21
Age of Ani = 21 years
Age of Biju = 21 + 3 = 24 years
Concept Insight: In this problem, ages of Ani and Biju are the unknown quantities. So, we represent them by variables x and y. Now, note that here it is given that the ages of Ani and Biju differ by 3 years. So, it is not mentioned that which one is older.

-100 + 10t = 20
10t = 120
t = 12
From equation (1), we obtain:

ABCD is a cyclic quadrilateral such that A = (4y + 20)o,
B = (3y - 5)o,
C = (-4x)o and
D = (7x + 5)o. Find the four angles.
We know that the sum of the measures of opposite angles in a cyclic quadrilateral is 180°. A +
C = 180
4y + 20 - 4x = 180
-4x + 4y = 160
x - y = -40 ... (1)
Also, B +
D = 180
3y - 5 - 7x + 5 = 180
-7x + 3y = 180 ... (2)
Multiplying equation (1) by 3, we obtain:
3x - 3y = -120 ... (3)
Adding equations (2) and (3), we obtain:
-4x = 60
x = -15
Substituting the value of x in equation (1), we obtain:
-15 - y = -40
y = -15 + 40 = 25 A = 4y + 20 = 4(25) + 20 = 120o
B = 3y - 5 = 3(25) - 5 = 70o
C = -4x = -4(-15) = 60o
D = -7x + 5 = -7(-15) + 5 = 110o
Concept insight: The most important idea to solve this problem is by using the fact that the sum of the measures of opposite angles in a cyclic quadrilateral is 180o. By using this relation, two linear equations can be obtained which can be solved easily by eliminating a suitable variable.

One says, "Give me a hundred, friend! I shall then become twice as rich as you". The other replies, "If you give me ten, I shall be six times as rich as you". Tell me what is the amount of their (respective) capital?
Let the money with the first person and second person be Rs x and Rs y respectively.
According to the question,
x + 100 = 2(y - 100)
x + 100 = 2y - 200
x - 2y = -300 ... (1)
6(x - 10) = (y + 10)
6x - 60 = y + 10
6x - y = 70 ... (2)
Multiplying equation (2) by 2, we obtain:
12x - 2y = 140 ... (3)
Subtracting equation (1) from equation (3), we obtain:
11x = 140 + 300
11x = 440
x = 40
Putting the value of x in equation (1), we obtain:
40 - 2y = -300
40 + 300 = 2y
2y = 340
y = 170
Thus, the two friends had Rs 40 and Rs 170 with them.
Concept insight: This problem talks about the amount of capital with two friends. So, we will represent them by variables x and y respectively. Now, using the given conditions, a pair of linear equations can be formed which can then be solved easily using elimination method.

If x = a, y = b is the solution of the system of equations x - y = 2 and x + y = 4, then the values of a and b are, respectively
- 3 and 1
- 3 and 5
- 5 and 3
- -1 and -3
Since x = a and y = b is the solution of given system of equations x - y = 2 and x + y = 4, we have
a - b = 2 ….(i)
a + b = 4 ….(ii)
Adding (i) and (ii), we have
2a = 6 ⇒ a = 3
⇒ b = 4 - 3 = 1
Hence, correct option is (a).
