A
$$2000$$

B
$$1500$$

C
$$1200$$

D
$$3000$$

Solution

$${ 360 }^{ o }$$ is equivalent to $$6000$$ p.m
$$\therefore$$ $${1}^{o}$$ is equivalent $$\cfrac { 6000 }{ 360 } $$
$$\Rightarrow { 120 }^{ o }$$ (corresponding to misc.)$$=\cfrac { 6000 }{ 360 } \times 120=2000Rs.$$
Question 8
1 / -0

The following data gives the distribution of monthly expenses under different heads.

A
$$20^{\circ}$$

B
$$80^{\circ}$$

C
$$85^{\circ}$$

D
$$120^{\circ}$$

Solution

$$Rs. 900$$ sweeps $$\angle 360^{\circ}$$
$$Re. 1$$ sweeps $$\dfrac {360^{\circ}}{900}$$
$$Rs. 200$$ sweeps $$\dfrac {360}{900}\times 200 = 80^{\circ}$$.
Question 9
1 / -0

Allocations to various sectors of the yearly budget for S. $$1000$$ crores are represented by the following pie diagram. The expenditure (in rupees) on agriculture is

A
$$250$$ crores

B
$$150$$ crores

C
$$300$$ crores

D
$$200$$ crores

Solution

$${ 360 }^{ o }\rightarrow Rs.1000crore\quad ,{ 1 }^{ o }\rightarrow Rs.\cfrac { 1000 }{ 360 } $$
Also, expenditure of agriculture is equivalent to $$180-54-54={ 72 }^{ o }$$
$$\Rightarrow { 72 }^{ o }\rightarrow \cfrac { 1000 }{ 360 } \times { 72 }^{ o }=Rs.200\quad crores$$
Question 10
1 / -0

In a test in Mathematics, $$20$$% of the students obtained "first class". If the data are represented by a Pie-Chart, what is the central angle corresponding to "first class"?

A
$${20}^{o}$$

B
$${36}^{o}$$

C
$${72}^{o}$$

D
$${144}^{o}$$

Solution

The Pie Chart is a part of Circle,

Total Central Angle is $$360^o$$

So, $$360^o=100\%$$
$$\Rightarrow \dfrac{360^o}{100}=1\%$$

So, $$20\%$$ $$=\dfrac{360^o}{100}\times 20=72^o$$
