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?

A.
24
B.
27
C.
40
D.
None of these

Solution:

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.

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

A.
Rs 1,500
B.
Rs 1,000
C.
Rs 750
D.
None of these

Solution:

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

QUESTION: 104

What would be the maximum value of Q in the following equation?
5P9+3R7+2Q8=1114

A.
8
B.
7
C.
5
D.
None of these

Solution:

+ 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

QUESTION: 105

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

A.
- 5 3 , 6 5
B.
5 3 , - 6 5
C.
- 4 3 , 11 3
D.
4 3 , - 11 3

Solution:

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

QUESTION: 106

If α and β are the roots of the equation x²+2x+1=0, then the equation whose roots are 1/α and 1/β is

A.
x²+ 1 2 x+ 1 2 =0
B.
x²+x+ 1 2 =0
C.
x²+ 1 2 x+1=0
D.
x²+2x+1=0

Solution:

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 x² - ( 1 α + 1 β ) x + ( 1 α . 1 β ) = 0
⇒ x² - (-2x) + 1 = 0
⇒ x² + 2x + 1 = 0

QUESTION: 107

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

A.
15 cm²
B.
30 cm²
C.
10 cm²
D.
none of the above

Solution:

Let the hypotenuse = x cm
Then the other side is (x - 8) cm
By Pythagoras theorem
(x - 8)² + (12)² = x²
⇒ x² + 64 - 16x + 144 = x²
⇒ -16x = -208
⇒ x = 208 16 = 13 cm
∴ Hypotenuse = 13cm
so the other side = (13 - 8) = 5cm
Area = 1 /2 x 12 x 5
= 30cm²

QUESTION: 110

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:

A.
11 years
B.
14 years
C.
15 years
D.
None of these

Solution:

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

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

A.
130
B.
125
C.
120
D.
100

Solution:

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
