MCQ

Find the correct answer from the alternatives given. Different expenditures incurred on the construction of a building were shown by a pie diagram. The expenditure $Rs. 45,000$ on cement was shown by a sector of central angle of $75^\circ$ . What was the total expenditure of the construction?

✓
$2,16,000$
B
$3,60,000$
C
$4,50,00$
D
$7,50,000$

Answer

Correct option: A.

$2,16,000$

The pie diagram shows, the central angle for expenditure on cement $= 75^\circ$
Also, expenditure on cement $= Rs. 45,000$
We know that,
Central angle for expenditure on cement $=\frac{\text { Expenditure on cement }}{\text { Total expenditure on the contruction }} \times 360^{\circ} $
$ \Rightarrow \text { Total expenditure on the construction }=\frac{\text { Expenditure on cement }}{\text { Central angle for expenditure on cement }} \times 360^{\circ} $
$ \Rightarrow \text { Total expenditure on the construction }=\frac{45000}{75^{\circ}} \times 360^{\circ}$
$\Rightarrow$ Total expenditure on the construction $= 216000$
Thus, the correct option is $(A).$

Do the following activity to draw tangents to the circle without using the center of the circle.

Draw a circle with radius 3.5 cm and take any point C on it.
Draw chord CB and an inscribed angle CAB.
With the center A and any convenient radius, draw an arc intersecting the sides of angle BAC in points M and N.
Using the same radius, draw an arc intersecting the chord CB at point R.
Taking the radius equal to d(MN) and center R, draw an arc intersecting the arc drawn in the previous step. Let D be the point of intersection of these arcs. Draw line CD. Line CD is the required tangent to the circle.

A line is parallel to one side of triangle which intersects remaining two sides in two distinct points then that line divides sides in same proportion.

Given: In $\triangle A B C$ line I || side $B C$ and line I intersect side $A B$ in $P$ and side $A C$ in $Q$.
To prove: $\frac{ AP }{ PB }=\frac{ AQ }{ QC }$
Construction: Draw $CP$ and $BQ$
Proof: $\triangle APQ$ and $\triangle PQB$ have equal height.
$\left.\frac{ A (\Delta APQ )}{ A (\Delta PQB )}=\frac{[}{ PB } \quad \ldots . . \text { (i) [areas in proportion of base }\right]$
$\frac{ A (\Delta APQ )}{ A (\Delta PQC )}=\frac{[}{ QC } \ldots . . . \text { (ii) [areas in proportion of base] }$
$\triangle P Q C$ and $\triangle P Q B$ have [____ ] is common base.
Seg PQ \| Seg BC, hence height of $\triangle A P Q$ and $\triangle P Q B$.
$A (\triangle PQC )= A (\Delta \ldots, \ldots \text {.....(iii) }$
$\frac{ A (\Delta APQ )}{ A (\Delta PQB )}=\frac{ A (\Delta \ldots)}{ A (\Delta \ldots \ldots[( i ) \text {, (ii), and (iii)] }}$
$\frac{ AP }{ PB }=\frac{ AQ }{ QC } \quad \ldots . . .[( i ) \text { and (iii)] }$
