MCQ 11 Mark

The point $(3, 4)$ is at a distance of:

A
$3$ from both the axis.
B
$4$ from both the axis.
✓
$4$ from the $x$ axis and $3$ from $y$ axis.
D
$3$ from $x$ axis and from $y$ axis.

Answer

Correct option: C.

$4$ from the $x$ axis and $3$ from $y$ axis.

We know that, the $x-$coordinate is the distance of the point from $Y-$axis and that of $y-$coordinate is the distance from $X-$axis.
Hence, the point $(3, 4)$ is at a distance of $4$ from the $X-$axis and $3$ from $Y-$axis.

MCQ 21 Mark

Comparison of parts of a whole may be done by a:

A
Bar graph.
✓
Pie chart.
C
Linrar graph.
D
Line graph solution.

Answer

Correct option: B.

Pie chart.

There are various ways to represent and compare the data. One of them is pie chart.
Pie chart is a pictorial representation of the data in which the whole is represented by a circle and the parts, by non-intersecting adjacent sectors.
Hence, comparison of parts of a whole may be done by a pie chart.

MCQ 31 Mark

Data was collected on a student’s typing rate and graph was drawn as shown below. Approximately how many words had this student typed in $30$ seconds$?$

A
$20$
B
$24$
✓
$28$
D
$34$

Answer

Correct option: C.

$28$

Observing the graph, we see that the graph intersects the line $x = 30$ just below the point $(30, 30),$ which is the intersection of the lines* $= 30$ and $y- 30.$
Since, the $X-$axis represents the time (in seconds) and the $Y-$axis represents the number of words typed, therefore we conclude that the students had typed approximately $28$ words In $30s.$

MCQ 41 Mark

In the given graph the coordinates of point $x$ are:

A
$(0, 2)$
B
$(2, 3)$
✓
$(3, 2)$
D
$(3, 0)$

Answer

Correct option: C.

$(3, 2)$

The foot of the perpendicular drawn from the indicated point on $X-$axis is at a distance of $3$ units from the origin.
The x-coordinate of the point is $3.$
Again, the perpendicular drawn from the given point on $Y-$axis meets the $Y-$axis at a point which is at a distance of $2$ units from origin.
The y-coordinate of the point is $2.$
Hence, the coordinates of the point are $(3, 2).$

MCQ 51 Mark

In the given graph the letter that indicates the point $(0, 3)$ is:

A
$P$
B
$Q$
✓
$R$
D
$S$

Answer

Correct option: C.

$R$

The letter that indicates the point $(0, 3)$ is $R$ as it lies on the $Y-$axis at a distance of $3$ units from the origin.
The coordinates of the point $P$ and Sare $(3, 0)$ and $(3, 3)$, respectively.

MCQ 61 Mark

A point which lies on both the axes is:

✓
$(0, 0)$
B
$(0, 1)$
C
$(1, 0)$
D
$(1, 1)$

Answer

Correct option: A.

$(0, 0)$

We know that, the axes are two mutually perpendicular lines intersecting each other at the point $(0, 0)$ also known as the origin.
Hence, the point which lies on both the axes is $(0, 0).$

MCQ 71 Mark

Which graphs of the following represent the table below$?$

Length of Side of a Square	$1$	$2$	$3$	$4$	$5$
Perimeter	$4$	$8$	$12$	$16$	$20$

Answer

Correct option: D.

Here, the lengths of sides of squares are represented on $X-$axis and their perimeters are represented on $Y-$axis.
The points are $(1, 4), (2, 8), (3, 12), (4, 16)$ and $(5, 20).$
Now, observing all the 4 graphs carefully we see that these points lie on the graph $(d).$

In the given figure the position of the book on the table may be given by:

A
$(7, 3)$
✓
$(3, 7)$
C
$(3, 3)$
D
$(7, 7)$

Answer

Correct option: B.

$(3, 7)$

The book is at a distance of $3$ units from $Y-$axis and $7$ units from $X-$axis.
Hence, the position of the book on the table is given by $(3, 7).$

MCQ 91 Mark

A graph that displays data that changes continuously over periods of time is:

A
Bar graph.
B
Pie chart.
C
Histogram.
✓
Line graph.

Answer

Correct option: D.

Line graph.

Line graph is an important way to represent and compare the data which varies continuously.
A line graph displays the relation between two varying quantities.
In a line graph, we connect all the points by a line segment while in bar graph and histogram, we use rectangles of uniform width.

MCQ 101 Mark

The coordinates of a point at a distance of $3$ units from the $x$ axis and 6 units from the $y$ axis is:

A
$(0, 3)$
B
$(6, 0)$
C
$(3, 6)$
✓
$(6, 3)$

Answer

Correct option: D.

$(6, 3)$

We know that, the $x-$coordinate is the distance of the point from /-axis and the $y-$coordinate is the distance of the point from $X-$axis.
Hence, the coordinates of the required point are $(6, 3).$
