If the expenditure of Company

$Y$ in

$1997$ was

$Rs. 220$ crores, what was its income in

$1997$ ?

0%
$Rs. 312$ crores
0%
$Rs. 297$ crores
0%
$Rs. 283$ crores
0%
$Rs. 275$ crores

Explanation

Profit percent of Company

$Y$ in

$1997 = 35.$
Let the income of Company

$Y$ in

$1997$ be $$Rs. x$$ crores.
Then,

$\displaystyle 35=\frac { x-220 }{ 220 } \times 100\Rightarrow x=297$

$\displaystyle \therefore$ Income of Company

$Y$ in

$1997 = Rs. 297$ crores.

Explanation

No. of vehicles manufactured by company Y in

$2000 = 128000$

No. of vehicles manufactured by company Y in

$2001 = 107000$

Required difference = (128000 - 107000) = 21000.

State whether the following statements are True or False ?
A point lies on y - axis at a distance of

$2$ units from the x- axis. Then its coordinate are

$\left(2,0\right)$ .

0%
True
0%
False

Explanation

Any point which lies on the y - axis of the form

$\left(0,y \right)$ . Its coordinate are

$\left(2,0\right)$ . Hence, the given statement is False.

The coordinates of the origin are

$(0, 0)$ .

0%
True
0%
False

Explanation

$\textbf{Step 1:Find the co-ordinates of origin}$

$\text{Origin denoted by O is the centre of the co-ordinate system}$

$\text{Origin lies on the intersection of the x-axis and y-axis}$

$\therefore \text{At origin,x=0 and y=0}$

$\Rightarrow O=(0,0)$ .

$\textbf{Therefore It is true that Co-ordinates of origin are(0,0)}$

The point at which the two coordinate axes meet is called the

0%
abscissa
0%
ordinate
0%
origin
0%
quadrant

Explanation

The points at which the two coordinate axes meets is called the origin.
Hence,

$\left(C\right)$ is the correct answer.

During which periods did the patient's temperature showed an upward trend?

0%
9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 2 p.m. to 3 p.m.
0%
9 a.m. to 10 a.m., 10.30 a.m. to 11.30 a.m., 2 p.m. to 3 p.m.

0%
9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 1 p.m. to 2 p.m.

Explanation

Whenever there is an increase in the value of

$y - axis$ as the time(on

$x - axis$ ) passes by, there is an upward trend.
Thus, the patient shows an upward trend between

$9 am - 10 am$ ,

$10 am - 11 am$ and

$2 pm - 3 pm$

Hence, option A is correct.

Explanation

From the given graph, we can observe that the patient temperature

$38.5^0C$ was at

$12$ noon

The patients temperature at 1 p.m. is:

0%
$37.0$ C
0%
$39.5$ C
0%
$36.5$ C
0%

How much distance did the car cover during the period 7.30 a.m. to 8 a.m?

0%
$20$ km
0%
$40$ km
0%
$80$ km
0%
$100$ km

Explanation

Using the information provided in the table, we can plot the graph shown above, taking the time on the

$x-axis$ and the distance (in km) on the

$y-axis$ .

From the above graph, we can observe that at

$7:30\ am$ , the distance traveled is

$100\space km$ and at

$8:00\ am$ , the distance traveled is

$120 \space km$ .

Therefore, the distance covered during the period

$7:30$ and

$8:00$ is

$120-100=20\space km$

Hence, option A is correct.

Draw a graph for the given information with suitable scales on the axes and answer the following question.

The time when the car had covered a distance of

$100$ km since its start is:

0%
