MOST IMPORTANT quantitative aptitude - 2 EXERCISES
The following question based on Mensuration topic of quantitative aptitude
In the figure given above, AB is a diameter of the circle with centre O and EC = ED. What is ∠EFO?
(a) 25°
(b) 15°
(c) 20°
(d) 30°
The correct answers to the above question in:
Answer: (c)
The Given,
⇒ ∠EDC = ∠ECD = 35°
Since, ∠OCD = 55°
Then, ∠OCE = 20°
By using then theorem that triangle on the same segment of a circle makes as equal angles.
Here, OE is a segment, which makes a ΔOFE and ΔOCE.
Therefore, ∠OCE = ∠EFO = 20°

Question : 2
Assertion (A)
Triangles on the same base and between the same parallel lines are equal in area.
Reason (R)
The distance between two parallel lines is same everywhere.
a) A is true but R is false
b) Both A and R individually true and R is the correct explanation of A
c) Both A and R are individually true but R is not the correct explanation of A
d) A is false but R is true
Answer »Answer: (b)
A. By the properties of triangle, it is true.
R. It is also true that the distance between two parallel lines is same everywhere.
Hence, A and R are true and R is the correct explanation of A.
Question : 3
The cross section of a canal is a trapezium in shape. If the canal is 7 metres wide at the top and 9 metres at the bottom and the area of cross-section is 1280 square metres, find the height of the canal.
a) 154 metres
b) 160 metres
c) 172 metres
d) None of these
Answer »Answer: (b)
Let the height of canal = h.
Then, area of canal = $1/2$ × h(9 + 7)
or = 1280 = $1/2$ h(16)
∴ h = ${1280 × 2}/{16}$ = 160m
Question : 4
In the given triangle, AB is parallel to PQ. AP = c, PC = b, PQ = a, AB = x. What is the value of x?
a) $b + {ca}/b$
b) $a + {ab}/c$
c) $a + {bc}/a$
d) $a + {ac}/b$
Answer »Answer: (d)
In ΔABC and ΔPQC,
∴ ${PC}/{AC} = {PQ}/{AB}$
⇒ $b/{c + a} = a/x$
∴ x = ${a(c + b)}/b = {ac}/b + a$
Question : 5
Using the data in the above question, what is the breadth of the rectangle ?
a) 8
b) 6
c) 12
d) 10
Answer »Answer: (a)
Breadth of the rectangle is 8 units, as solved above
Question : 6
A cardboard sheet in the form of a circular sector of radius 30 cm and central angle 144º is folded to make a cone. What is the radius of the cone?
a) 21 cm
b) 12 cm
c) 18 cm
d) None of these
Answer »Answer: (b)
length of the are = 2 π r $(θ/{360º})$
Radius of arc(r) = 30 am
Length of the arc = 2πr = 2π × 30 × ${144}/{360}$ = 24π
Let the radius of the cone = R ∴ 2πR = 24π
⇒ R = ${30 × 144}/{360}$ = 12cm
