Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 14
The numbers in the first row form a series 1^{2}, 2^{2}, 3^{2}.

So, missing number in the first row =4^{2}=16.

The numbers in the second row form the series, 1, 2, 3, 4.

The numbers in the third row form the series 2, 4, 6.

So, missing number in the third row =6+2=8.

So, missing number in the first row =4

The numbers in the second row form the series, 1, 2, 3, 4.

The numbers in the third row form the series 2, 4, 6.

So, missing number in the third row =6+2=8.

Akbar will turn 50 when his son Jehangir turns 18. What will be Akbar's age when it will be exactly 5 times that of Jehangir?

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 103

Let us suppose when jahangir's age will be 5 times that of akabar's age will be 50 - x

Hence jahangir's age wil be 18 - x

Hence (50 - x) = 5(18 - x)

⇒ 50 - x = 90 - 5x

⇒ 4x = 40

⇒ x = 10

Hence akbar's age will be 50 - 10 or 40 years when jahangir's age was 8 years

SSC CPO Mock Test (Paper 1) - 4 - Question 107

Given that x+2 and x-3 are factors of x^{3} + ax + b, the values of a and b are

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 107

Let p(x) = x^{3} + ax + b

x + 2 is a factor of p(x)

So, p(-2) = 0

(-2)^{3} + a(-2) + b = 0

⇒ - 8 - 2a + b = 0

⇒ b - 2a - 8 = 0 .....(1)

x - 3 is a factor of p(x)

So, p(3) = 0

(3)^{3} + a(3) + b = 0

⇒ 27 + 3a + b = 0 .....(2)

Subtract equation (1) from (2) we get 5a + 35 = 0

⇒ 5a = - 35

⇒ a = -7

b = -6

SSC CPO Mock Test (Paper 1) - 4 - Question 108

If x = 1 2 (√3 + 1), then the value of 4x^{3} + 2x^{2} - 8x + 7 is-

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 108

If x = 1 2 (√3 + 1)

⇒ (2x - 1)^{2} = 3

⇒2x^{2} - 2x - 1 = 0

∴ 4x^{3} + 2x^{2} - 8x + 7

= 2x (2x^{2} - 2x - 1) + 3 (2x^{2} - 2x - 1) + 10

= 2x (0) + 3 (0) + 10 = 10

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 109

Area of the park minus the paths

= (200 - 3) (150 - 2)

= 197 x 147 sq. m

A man ordered 4 pairs of black socks and some pair of brown socks. The price of a black pair is double that of a brown pair. While preparing the bill,the clerk interchanged the number of black and brown pairs by mistake which increased the bill by 50%. The ratio of the number of black and brown pairs of socks in the original order was

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 130

Let x pairs of brown socks were ordered

Let P be the price of a brown pair

Therefore price of black pair of sock = 2P

Then 4P + 2Px = 1.5 (xP + 8P)

⇒ 4P + 2Px = 3 2 (xP + 8P)

⇒ 8P + 4Px = 3xP + 24P

⇒ Px = 16P or x = 16

The ratio of the number of black and brown pairs of socks in the original order was 1:4

Find the minimum number of cubes required to construct a cuboid of dimension 20cm x 16cm x 12cm ?

Detailed Solution for SSC CPO Mock Test (Paper 1) - 4 - Question 141

Volume of cuboid = 20 x 16 x 12 = 3840 cm^{3}

Since minimum no. of cubes required

So length of cube = HCF of 20, 16, 12 cm = 4

Volume of each cube = (4)^{3} = 64cm^{3}

minimum no of cubes = Vol. of cuboid Vol. of cube = 3840 64 = 60
