Present ages of Sameer and Anand are in the ratio of 5:4 respectively. Three years hence, the ratio of their ages will become 11:9 respectively. What is Anand's present age in years?

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 102

Let the present ages of Sameer and Anand be 5x years and 4x years respectively.

Then, 5x + 3 4x + 3 = 11 9

⇒ 9(5x + 3) = 11(4x + 3)

⇒ 45x + 27 = 44x + 33

⇒ 45x - 44x = 33 - 27

⇒ x = 6

∴ Anand's present age = 4x = 24 years.

SSC CPO Mock Test (Paper 1) - 3 - Question 103

If two tables and three chairs cost Rs 3500,while three tables and two chairs cost Rs 4,000,then the price of one table is

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 103

As per question

2T + 3C = 3500.....(1)

3T + 2C = 4000.....(2)

from equation(1)

2T = 3500 - 3C

⇒ T = 3500 - 3C 2

Putting value in equation (2)

3 x ( 3500 - 3C 2 ) + 2C = 4000

⇒ 10500 - 9C 2 + 2C = 4000

⇒ 10500 - 9C + 4C 2 = 4000

⇒ 10500 - 5C = 8000

⇒ - 5C = 800 - 10500

⇒ C = 2500 5 = 500

Putting value of 1 chair in equation (1)

2T + 3C = 3500

2T + 3 (500) = 3500

⇒ 2T = 3500 - 1500

⇒ T = 1000

SSC CPO Mock Test (Paper 1) - 3 - Question 104

What would be the maximum value of Q in the following equation?

5P9+3R7+2Q8=1114

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 104

+ 1 2 5 P 9 3 R 7 2 Q 8 11 1 4

⇒ 2 + P + R + Q = 11

So for maximum value of Q, P = R = 0

∴ Q = 11 - 2 = 9

SSC CPO Mock Test (Paper 1) - 3 - Question 105

If 5X + 6 (2 + X)(1 - X) = a 2 + x + b 1 - x , then the values of a and b respectively are

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 105

5x + 6 (2 + x)(1 - x)

= a 2 + x + b 1 - x

= a(1 - x) + b(2 + x) (2 + x)(1 - x)

or 5x + 6 = a(1 - x) + b(2 + x)

or 5x + 6 = (a + 2b) + x(b - a)

∴ a + 2b = 6 .....(1)

-a + b = 5 .....(2)

Solving (1) & (2) we get

3b = 11

b = 11 3 ,

a = 11 3 - 5 = - 4 3

SSC CPO Mock Test (Paper 1) - 3 - Question 106

If α and β are the roots of the equation x^{2}+2x+1=0, then the equation whose roots are 1/α and 1/β is

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 106

α + β = - 2

α . β = 1

1 α + 1 β = α + β αβ = -2

1 α . 1 β = 1 αβ = 1

The required equation is x^{2} - ( 1 α + 1 β ) x + ( 1 α . 1 β ) = 0

⇒ x^{2} - (-2x) + 1 = 0

⇒ x^{2} + 2x + 1 = 0

SSC CPO Mock Test (Paper 1) - 3 - Question 108

One side of a right triangle measures 12 cm and the difference between the hypotenuse and the other side is 8 cm. The area of the triangle is

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 108

Let the hypotenuse = x cm

Then the other side is (x - 8) cm

By Pythagoras theorem

(x - 8)^{2} + (12)^{2} = x^{2}

⇒ x^{2} + 64 - 16x + 144 = x^{2}

⇒ -16x = -208

⇒ x = 208 16 = 13 cm

∴ Hypotenuse = 13cm

so the other side = (13 - 8) = 5cm

Area = 1 /2 x 12 x 5

= 30cm^{2}

The average age of 15 students of a class is 15 years. Out of these, the average age of 5 students is 14 years and that of the other 9 students is 16 years. The age of the 15th student is:

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 110

Total age of 15 students = (15 x 15) years = 225 years

Total age of 5 students = (5x 14) years = 70 years

Total age of other 9 students = (9 x 16) years = 144 years

∴ Age of the 15th student = 225 - (70 + 144) = 225 - 214 = 11 years

SSC CPO Mock Test (Paper 1) - 3 - Question 111

The average of three numbers is 135. The largest number is 180 and the difference of the others is 25. The smallest number is

Detailed Solution for SSC CPO Mock Test (Paper 1) - 3 - Question 111

Let the numbers be x, y and z

⇒ x + y + z /3 = 135

⇒ x + y + z = 405

But let x = largest number i.e. 180

⇒ y + z = 225 .....(1)

Also, y - z = 25 .....(2)

Solving (1) and (2)

We get 2y = 250

⇒ y = 125

⇒ z = 125 - 25 = 100

Hence, the smallest number among the three numbers is 100
