SSC CPO Mock Test (Quant Apt) 3 - Question 3

Factors of(2x-3y)³+(3y-5z)³+(5z-2x)³ are

SSC CPO Mock Test (Quant Apt) 3 - Question 4
If 2x+3y=26; 2y+z=19 and x+2z=29,what is the value of of x+y+z?
Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 4
2x + 3y = 26 .....(i)
2y + z = 19 .....(ii)
x + 2z = 29 .....(iii)
from (ii) and (iii)
x + 2(19 - 2y) = 29
x + 38 - 4y = 29
x - 4y = - 9 .....(iv)
from (i), (ii) and (iv) we get
y = 4, x = 7, z = 11
∴ x + y + z = 4 + 7 + 11 = 22
SSC CPO Mock Test (Quant Apt) 3 - Question 5

If α, β, γ and Δ are the roots of the polynominal equation (x2 - 3x + 4)(x2 + 2x + 5)= 0, then the quardratic equation whose roots are α + β + γ + Δ and αβγΔ is

Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 5

α + β = 3, α.β = 4
γ + Δ = -2, γ.Δ = 5
α + β + γ + Δ = 3 - 2 = 1
α.β.γ.Δ = 4 × 5 = 20
Required quadratic equation is
x2 - (α + β + γ + Δ)x + (αβγΔ) = 0
x2 - x + 20 = 0

SSC CPO Mock Test (Quant Apt) 3 - Question 6

Diameter of two circular plates are respectively 18cm and 80 cm. The diameter of the plate which has an area equal to the combined area of two given plates is

Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 6

Combined area of two plates = π (9)2 + π (40)2
= π (81 + 1600)
= 1681 π cm2.
Let R be the Radius of plate, whose area is combined area of two plates.
Area of plate = πR2 = 1681 π
⇒ R2 = 1681
⇒ R = 41 cm.
Diameter = 2 x 41 = 82 cm

SSC CPO Mock Test (Quant Apt) 3 - Question 7

The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4?

Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 7

Let the cricket player makes x runs in his next innings
∴ 32 × 10 + x = 11 × 36
∴ x = 396 - 320 = 76

SSC CPO Mock Test (Quant Apt) 3 - Question 8

OABC is a rhombus whose vertices A, B and C lie on a circle with centre at O. If radius of circle is 10cm. The area of the rhombus

Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 8

If A, B, and C lie on the circle, O is the center of the circle, and the radius is 10 cm, then OA, OB, OC, AB, and BC must all measure 10 cm because OA, OB, and OC are all radii, and AB and BC are congruent because of congruent sides of a rhombus.
Hence, the area of the rhombus is twice the area of an equilateral triangle with sides that measure 10 cm.

SSC CPO Mock Test (Quant Apt) 3 - Question 9

Diagonals of a rhombus are in the ratio 3:4 and its area is 2400 cm2. Side of the rhombus is

Detailed Solution for SSC CPO Mock Test (Quant Apt) 3 - Question 9

Let the diagonals of a rhombus are 3K and 4K. Then
Area of rhombus = 1/2 x product of diagonals
2400 = 1/2 x 3K x 4K
or 400 = K2
or K = 200
∴ The Diagonals are 60 cm and 80 cm
we know that, if a be side of the rhombus and AC and BD be its diagonals then 
(AC)2 + (BD)2 = 4 × a2
or (60)2 + (80)2 = 4 × a2
or 3600 + 6400 = 4 × a2
or 10000 = 4a2
or 2500 = a2
or a = 50 cm
